CAUTION

CAUTION indicates a potentially hazardous situation that, if not avoided, may result in moderate to minor injury, equipment damage or loss of data. NOTE is given in situation requiring special attention.

NOTE

1.2.2.

Ingress of Fluids

Excessive amounts of fluids such as antiseptics, cleaning solutions or bodily fluids may damage internal components if they are allowed inside the equipment.

WARNING

The equipment is not rated for water-tight operation. Do not allow any liquids to leak into the equipment where they can cause electric shock, fires, and short circuits. If leakage does occur, ensure that all internal circuitry is completely dry before attempting to operate the equipment.

WARNING

Never store or operate the system in the presence of conductive fluids like water or saline solution unless the system is adequately protected by an approved bagging or draping system.

1-4

Introduction and Safety

1.2.3.

Electrical Shock

If the equipment must be serviced with the covers removed, observe the following precautions: Equipment that contains high power electrical components must be serviced only by personnel familiar with proper safety procedures for working near these components.

WARNING

Disconnect AC power (and battery packs if used) before discharging static electricity in components such as electrolytic capacitors and high voltage cables. Failure to heed this message will result in death or severe personal injury.

WARNING

Allow adequate time for static charges to discharge through bleeder resistors. Use a high wattage resistor when discharging circuits to avoid burns.

WARNING

Have someone watch while you work near high voltages. This person must remain clear of all circuitry and be prepared to turn off the power to the system and render aid in an emergency.

WARNING

High voltage cables, electrolytic capacitors, and CRTs can retain a dangerous static charge for long periods after power has been removed. Some devices can acquire a charge spontaneously without direct contact with other circuitry. Do not touch these components unless power has been completely removed and they have been discharged.

WARNING

CAUTION

Never operate the system unless all safety ground wires (green wire with a yellow stripe) and related components are fastened in place. Dangerous electrical shock and improper equipment operation can otherwise result.

CAUTION

Remove all metal rings and watchbands before working on system circuitry. Skin burns and damage from involuntary muscle contractions can result if metal jewelry shorts electrical circuits.

1.2.4.

Explosion

If an abnormal condition occurs, such as the room fills with flammable gas, steps must be taken to prevent the gas from contacting components within the equipment. Follow these guidelines: 1.

Do not turn the system on or off.

2.

Do not un-plug or plug-in system or peripheral equipment power cords.

3.

Do not operate light switches or other electrical equipment.

The C-Arms derive their name from the rigid, C-shaped weldment that supports the Image Intensifier, collimator, CCD Camera, and X-ray tube. These components together are commonly called the “C”, and the entire assembly from the casters up is known as the “C-Arm”. The X-Ray tube generates an X-ray beam that is shaped and oriented by the collimator. After passing through patient anatomy, the beam is directed onto a film cassette to produce a radiographic film image, or through the image intensifier and CCD camera, to convert the X-ray image to a video signal that is transmitted to the Workstation for display, processing, and storage.

Brivo OEC 715/785/865/865 Mobile C-Arm X-Ray Product Service Manual

Power Input AC main power input:  This is a AC main input with bias ±15%. It supports multiple rated voltages configuration with 100V/110V/120V/200V/220V/230V/240VAC (RMS). Secondary side of main transformer:  Another input comes from the secondary side output of main transformer. The rated voltage is 220V (RMS) and 28V (RMS) for up-down board and mainframe.

Power On Board +24V  When the main input power is ok with no gross over and under voltage condition, the relay K6 is activated and the AC voltage of secondary side of start_up transformer (BT2) is applied at the D7 (2W06), then the rectified DC voltage connected to the input pins of U4 (LM317T) and the output voltage is about +24VDC by the configuration of R10 and R8. The +24V voltage is mainly to drive relays and get other necessary DC power on board. VCC_+12V  To make sure the WKS on/off control relay (K7) work properly in AC main power lost condition, the VCC_+12V DC power use dual power method by the simple parallel of CMPTR_+12V and +12V. CMPTR_+12V is connected the +12V power from computer and +12V is generated from the conversion of low dropout regulator LM2940CT-12(D26). +10V, +5V, +3.3V  To get more accurate voltage reference in voltage comparison circuit, the +10V power is achieved by the +10V precision voltage reference REF01SC3 (D9).

+5V power is generated by the LM2940CS-5.0 (D8) and +3.3V power is generated by the LM1084-3.3.(U5)

An Altera CPLD U1 is used as main controller on the board; it controls most of the relays on the board, generates the signal by the user interface and communicates with SIB board

Power on scheduling To achieve the inrush current suppression for the primary side of the main transformer, power resistors R (15Ohm, 50W) shall be used in system configuration. Approximately 2 seconds after power with no gross over/under voltage fault is applied by the relay K1, relay K2 closes, bypassing the resistors R, reducing IR voltage drop, and allowing them to cool. To avoid the risk that the resistor R will be heated and burned when the K2 is in failure, relay K1 shall be energized for only about 1s. Similarly, to achieve the inrush current suppression for the mainframe side, power resistors R(15Ohm,50W) shall be also used in the secondary side of main transformer. The 220V voltage winding is applied to the mainframe by the K3 and K4. When the secondary voltage of main transformer with no load is OK, K3 will be energized first, then the K4 closes to shorten the R to reduce the power loss, the K3 will be energized for about 1s to avoid the risk that the resistor R will be heated and burned when the K4 is in failure. The 28V voltage winding is directly applied by the relay K5.

UPS status for Power On/Off Normal Power off system 1. 2. 3. 4.

Grounding Connection All the grounds of power are connected by mother board with one point strategy.

Collimator Control Collimator control includes - Collimator Shutter open/close control - Collimator Shutter rotation control - Collimator Iris open/close control MCU gets user’s command from Control panel, and sends setting value of position information of Shutter and Iris to Collimator by SPI bus. Meanwhile, MCU gets feedback value of position of Shutter and Iris from Collimator by analog signal. Analog signals (IRIS_POS_F/SHUT_ROT_POS_F/SHUT_WIDTH_POS_F), which are from collimator control board to MCB, are sampled by ADC unit of MCU finally. MCB sends digital setting values to CCB via SPI bus. The voltage level of all the digital signals from MCB to collimator control board is transformed from +3.3V to +15V by optical coupling circuit.

Filament Control The voltage level of all the digital signals between MCB and filament control board are transformed from +3.3V to +15V by optical coupling circuit. MCB sends digital setting values to DAC with SPI bus. Differential operational amplifier circuit amplifies differential signals MA_CAT and KV_GND from tube, and outputs mA_sample to PI control circuit. PI amplifies mA_sample and two signals out from DAC circuit, mA_setting and mA_preheat, and outputs signal MAC to filament control board. The structure of PI control circuit is shown as follows. The difference between signal mA_sample and mA_setting is output to proportional and integral circuit, respectively. The outputs of those circuits are added by signal mA_preheat, then the result signal MAC is output to filament control board. The theory of PI control circuit is as follows. The tube current is controlled by signal MAC. Initially MAC equals mA_preheat, which is a preset value corresponding to the user setting value mA_setting. Signal mA_sample is the sample of tube current. If mA_sample is different with mA_setting, the error will be amplified, integrated and added to signal mA_preheat by PI control circuit. Then the output signal MAC of PI control circuit controls tube current in order to make the error be smaller. This process goes on, and finally mA_sample value is equal to mA_setting value, and PI control is stable.

KV Control After optical coupling circuit transforms the voltage level of 6 alarm signals, those signals will be sampled and recorded by registers in Peripheral Controller. MCU will get these alarm status by local bus between Peripheral Controller and MCU. Digital signal EXPOSURE_COMMAND and SAFETY_EN are from MCB to KV control board, whose voltage level is transformed from +3.3V to +15V by optical coupling circuit. Analog signal KV_FEEDBACK_OUTPUT, which is from KV control board to MCB, is amplified (or adjusted) by operational amplifier circuit and sampled by ADC unit of MCU finally. Analog signal KV_SET_INPUT is from MCB to DAC through SPI bus, then to KV control board, and amplified (or adjusted) by operational amplifier circuit.

System Overview

Camera Control FRAME_SYNC and Last Image Hold (LIH) signals are critical for exposure control and are addressed in exposure module. MCU sends GAIN information to camera to control the brightness of image. Digital signals LIH is through optical coupling circuit from Peripheral controller of MCB to Camera. Digital signal FRAME_SYNC is from Camera to MCB. It is the global synchronization signal of X-Ray control function, so it acts as clock and interrupt signal to peripheral controller and MCU, respectively. GAIN signal from MCB to camera is through RS485 bus.

Image Intensifier Control II control here means II field switch only. F1/F2 signals are controlled by MCU directly. Digital signals (F1/F2) are from MCB to II. The voltage level of those signals is transformed from +3.3V to +24V by optical coupling circuit. MCB outputs IDRG_HC signal to control the relay. When the relay is close, II_PWR is connected with +24V and II_GND is connected with GND_+24V. Therefore, II is power-on. When the relay is open, II_PWR and II_GND are both connected to GND_+24V, and then II is power-off.

Sealing Board Analog signals KV_GND and MA_CAT are the anode and cathode of mA current signal, respectively. The current transforms to voltage signal by flowing through a resistor. ADC unit of MCU in MCB samples this signal after its scale is transformed to 0-2.5V by operational amplifier circuit. There are two temperature measurement circuits in sealing board. One’s output is analog signal OIL_TEMP, whose scale is 0-2V. ADC unit of MCU in MCB samples this signal after its scale is transformed to 0-2.5V by operational amplifier circuit. MCU will compare this value with preset threshold to generate oil tank warm warning and hot alarm. The other’s output is connected/open status between THERMAL_SWITCH_A and THERMAL_SWITCH_B. If the temperature of oil tank is higher than a preset threshold, the relationship between THERMAL_SWITCH_A and THERMAL_SWITCH_B changes from connected to open. This relationship is transformed by optical coupling circuit, which is shown as follows. The output of optical coupling circuit is connected to GPIO (General Purpose Input Output) of MCU. When THERMAL_SWITCH_A and THERMAL_SWITCH_B are connected, transistor is open. Then optical coupling do not work, and signal OUTPUT is high logic at +3.3V. Otherwise, when THERMAL_SWITCH_A and THERMAL_SWITCH_B are open, signal OUTPUT is low logic at 0V.

Workstation Communication Communication interface between WK and MCB is full duplex RS485 bus.

Control Panel SPI (Serial Peripheral Interface) is used as communication layer protocol between MCB and Control panel. Optical coupling circuit is used as physical layer. Because signals are transported on a long distance line, they are prone to interfering by noise. So voltage promotion technical has been adopted because of its width voltage threshold. The signal level is changed from +3.3V to +15V, and changed back to +3.3V by optical coupling circuit. Digital signal YELLOW_LED control the exposure LED on control panel, and the changes of signal level are the same as SPI signals. MCU in MCB connects MAX6954 and MAX7301 in Control panel with SPI bus. MCU is master of SPI bus, while MAX6954 and MAX7301 are slaves. Master initiates every communication session, and only one slave, which

2-21

Brivo OEC 715/785/865/865 Mobile C-Arm X-Ray Product Service Manual

is selected by chip selection signal of bus, will respond the session. MCU reads or writes the registers in slaves to get the status and control the output of slave. MAX6954 is a key and LED controller. When a key press action is detected, an interrupt will route to MCU. Then MCU will get the key matrix status to identify which key has been pressed by reading the status registers in MAX6954. Meanwhile, MCU changes the 7-segent LED display by writing the control registers in MAX6954. MAX7301 is a LED controller. Similarly to MAX6954, MCU changes the LED display by writing the control registers in MAX7301.

User Interface Control Key Switch As shown in Figure 17, the connected/open status between ON (or X-RAY OFF) and COMMON is transformed to digital signal Exp_lift_column_enable (or Lift_column_enable) by optical coupling circuit. MCU get the status of key switch by sampling this signal. The optical coupling circuit is shown as follows. Signal ON corresponds to signal INPUT_A, and signal COMMON corresponds to signal INPUT_B. Then signal ON corresponds to signal OUTPUT. When INPUT_A and INPUT_B are connected, transistor in optical coupler is open and OUTPUT is 0V. Otherwise, OUTPUT is +3.3V.

Hand Switch The circuit and theory are similar to key switch except checking the switch stuck error. The switch stuck error occurs when one of HAND_SWITCH and HAND_SECURITY keeps inactive for more than 10 seconds after the other has been active. As shown in Figure xx, exposure command line and security line are independent by using different routes.

Foot Switch The circuit and theory are similar to hand switch include checking the switch stuck error.

Emergency Switch The circuit and theory are similar to voltage transmit circuit.

Removable Filter The circuit and theory are similar to switch.

Indicator Peripheral controller of MCB outputs digital signal INDICATOR_+24V corresponding to signal INPUT shown in Figure 17, which is 0V/+3.3V voltage level. Then optical coupling circuit transforms it to digital signal X_RAY_ON corresponding to signal OUTPUT, which is 12mA current. Signal X_RAY_ON connects to one termination of indicator, and the other termination connects to GND_+24V, which is the reference of +24V. When X_RAY_ON is active, the indicator will light.

Buzzer 6 different tones are generated. -

System Overview

The circuit of buzzer control uses audio operational amplifier.

Auto Brightness Control MCU gets IBS (Image Brightness Signal) from WKS through RS485, and looks up the ABC (Auto Brightness Control) table with IBS value, and get the setting value of kV and mA. Finally, the kV and mA control analog signals are output to KV control board and filament control board through DAC and operational amplifier circuit or PI circuit sequentially.

Manual kV Setting Control panel samples the manual kV setting value, and transports it to MCU by SPI bus. MCU looks up the responding data and sets DAC circuit. Operational amplifier circuit amplifies kV control signal from DAC, and outputs signal KV_SET_INPUT to kV control board finally.

Manual mA Setting Control panel samples the manual mA setting value, and transports it to MCU by SPI bus. MCU looks up the responding data and sends out signals to DAC circuit. The mA control analog signals, KVC and MAC, are output to filament control board through DAC and PI circuit sequentially.

mAs Control The setting value of mA is 20mA (or 10mA) in mAS mode. mA sample signal is transformed to pulse by VFC circuit. The pulse is used as clock signal of down counter in peripheral controller. When mAS mode is set, the mAS time is set in down counter as the initial value. While exposure starts, down counter works at the same time. When the value of down counter reduces to 0, exposure stops.

High Level Fluoro Logically, there is a table that consists of 4 columns: input kV value, input mA value, output kV value and output mA value. MCU looks up the table by input kV and mA value, and gets output kV and mA value as kV and mA setting respectively, then outputs those setting.

Auto mA Calibration Because valid exposure period in each frame is smaller than 40 ms, response time from MAC signal set out to mA stable should be within a certain time. Meanwhile, the response time is related with the parameters of tube. The key parameter is the current of tube before exposure. If it is very near the current in exposure followed, the response time will be short enough to meet the requirement. Therefore, the rational is that a preheat table is setup to provide the mA_preheat signal in section 6.3.4 Figure 5, which give out a proper current of tube before exposure, and PI control will control mA stable in several ms’ in exposure. Unfortunately, the variation exists among the parameters of tubes. Although the variation is small, unique preheat table should be setup for each tube. In order to get this unique preheat table, auto mA calibration process shall be as follows. - The variation is so small that a draft preheat table is generated from mass experiment, which is usable for calibration - MCU sends out mA_preheat signal according to the draft preheat table instead of MAC signal to filament board - Sample mA feedback (mA_sample signal in section 6.3.4 Figure 5) with ADC unit of MCU - Then the relationship between MAC and mA of the tube is gotten - Interpolation to get a unique preheat table of the tube, in which mA value is normalized

THEORY OF OPERATION Power Regulator This circuit is to translate the DC24V input to the DC+15V and DC+2.5V which would be used in the updown board. Devices 7815 and LM431 are used to realize this function. AC-DC Translate the AC28V input to the DC output. Up/down relays This function is to realize the up and down motion. Different polar voltage would be added to the lift column motor by these relays. Relay K9 is closed-normal. When the motor is forbidden motioning, K9 shall turn on and this closed-normal contact shall open. When the up motion is enabled, relays K1-K4 shall turn on and relays K5-K8 shall turn off. And the positive DC voltage shall apply to the lift column motor. The voltage of the signal MOTO1 shall higher than MOTO2 and the motor begins up motion. When the down motion is enabled, relays K5-K8 shall turn on and relays K1-K4 shall turn off. And the negative DC voltage shall apply to the lift column motor. The voltage of the signal MOTO2 shall higher than MOTO1 and the motor begins down motion. Up/down control relays This circuit is to control the relays in Up/down relays circuit according to the commands from Up/down Key Control & Delay circuit. Up/down Key Control & Delay This circuit is to translate the up, down, down_security signals to the UP_COMMAND and DOWN_COMMAND signals to control the relays and the motor motion. It includes two basic functions: delay control function and motion control function. - Motion control function When only the up key is pressed the UP_COMMAND signal shall be high level. When the motor is not at the proximity protect position and only the down key is pressed, the DOWN_COMMAND signal shall be high level. When the motor is at the proximity protect position and both the down key and down_security key are pressed, the DOWN_COMMAND signal shall be high level. When both of the up key and the down key are pressed the motor shall stop. The signal UP_COMMAND and the signal DOWN_COMMAND shall be low level.

- delay control function The Updown board shall receive the lift column up or down command and then drive the motor motion with a few milliseconds delay. The RC delay circuit is used to realize this function. Voltage Detector This function is to detect the DC voltage through the resistor divider. The output of this circuit is the input of the PMOSFET Driver circuit.

2-38

System Overview

PMOSFET Driver This circuit is to control the PMOSFET so that the DC voltage would not higher than 37V+/-5%. When the DC voltage is higher than 37V+/-5% the PMOSFET would turn off. When the DC voltage is lower than 29V+/-5% the PMOSFET would turn on. Motor Current Detector This circuit is to detect the motor current. There are two current limit values. One is for the up motion. The other is for the down motion. When the motor current is larger than the limit value, the overcurrent signal would send out to stop the motion. Key Switch Sensor This circuit is to detect the key switch signal to control the motor motion. When the key switch is at the OFF state the output of this circuit would be high level and the motor motion would be disabled. Motion DIS/ENA This circuit is to detect the UDB_ENABLE signal from MCB to control the motor motion. When the UDB_ENABLE signal is low level the output of this circuit would be high level and the motor motion would be disabled. Proximity Switch Protector This circuit is to detect the state of the proximity switch to control the motor motion. When the motor is down to the proximity protect position the output of this circuit would be high level and the motor would be stopped. Interlock Protector There are many factures to affect the motor motion including up key, down key, down_security key, motor current, key switch, proximity switch and motion DIS/ENA. This circuit is to combine these features to control Relay K9 and then to realize the control of the motor. - When any signal from motor current, key switch, proximity switch and motion DIS/ENA is to disable the motor motion, relay K9 would turn on and HL5 would be bright. The DC voltage of the motor would down to zero. And then the motor stops. - The interlock function of motor current and keys are realized in this circuit. When the motor current is overloaded the motor would be disabled to motion and HL4 and HL5 would be bright. Only when all the keys are released the HL4 and HL5 can be dark. And then the motor motion is enabled. - The interlock function of keys and proximity switch are realized in this circuit. When the motor down to the proximity protect position HL5 shall be bright and the motor shall stop. Only when all the keys are released the HL5 can be dark. And then press both the down key and the down_security key at the same time. The motor begins down motion.

System Overview

Dual Source/Sink Outputs: ±400 mA Peak

The switch frequency is 40KHz for X-ray generator. So the SG3525 should provide 40KHz PWM signal. Frequency is determined by adjusting the resistor connected with pin6 and capacitor connected with pin5. At this pin5 80KHz swath wave should be observed in oscillograph. The pin2 inputs variable voltage signal. Then this voltage signal enters the comparator through internal amplifier and generators PWM signal. PI ADJUSTOR X-ray generator provides stable kV when exposure. It needs to use feedback control to stabilized the output kV. PI adjustor is usually using at feedback control. There are 2 PI adjustors in kV control board, voltage PI adjustor and current PI adjustor. Voltage PI adjustor consists of amplifier U6-2 and resistor R28, R35, R50, R32, capacitor C27, C31,. Before entering the PI adjustor the set kV value subtracts the feedback kV value to send out error signal. This signal is sent to voltage PI adjustor. Current PI adjustor consists of amplifier U6-1 and resistor R44, R46, R47, capacitor C29, C30. The output signal from voltage PI adjustor subtracts the feedback current of inverter output to send out error signal. This signal is sent to current PI adjustor. Then the PI adjustor carries out the voltage signal and enters PWM generator SG3525. IGBT DRIVER KV control board consists of IGBT driver circuit. Usually the IGBT driver circuit must be insulated with control circuit and it still needs several independent power for IGBT gate driver. Agilent IC HCPL-316J is a highly Integrated power control device that incorporates all the necessary components for a complete, isolated IGBT gate drive circuit with fault protection and feedback into one SO-16 package. TTL input logic levels allow direct interface with a microcontroller, and an optically isolated power output stage drives IGBTs with power ratings of up to 150 A and 1200 V. A high speed internal optical link minimizes the propagation delays between the micro-controller and the IGBT while allowing the two systems to operate at very large common mode voltage differences that are common in industrial motor drives and other power switching applications. The feather is as follows. -

Drive IGBTs up to IC = 150 A, VCE = 1200 V Optically Isolated, FAULT Status Feedback SO-16 Package CMOS/TTL Compatible 500 ns Max. Switching Speeds

For the independent driver power supply kV control board consists of 4 channel independent power. Each channel can provide DC+18V and DC–4.7V power for HCPL-316J. Those DC power is rectified from AC power. The power interface connector is KJ7. It connected with driver power transformer. PROTECT CIRCUIT KV control board designed 6 protect circuits to protect the X-ray generator. KV lower protect circuit, kV higher protect circuit, Over current protect circuit, IGBT error protect circuit. DC bus error protect circuit, kV unbalance protect circuit. According to generator design requirement the kV output value range is 40kV-110kV. This kV board set protect circuit point is 25kV. That is if the kV value is lower than 25kV when X-ray generator is running the exposure can be disable. The kV control board drawing shows the protect circuit. When kV feedback signal KVT is higher than reference value in U10-1 the STOP signal is activated. At the same time led DS4 lightens. This protect circuit is enable after a time of 6ms which made by resistor R74 and capacitor C47 after giving the exposure command.

For the higher protect circuit point the value is set 120kV. When kV feedback signal KV- or kV+ is higher than reference value in U10-2 and U11-2 the STOP signal is activated. At the same time led DS5 lightens. Jumper W1 can disable this protect circuit. If jumper W1 is short circuit the higher protect circuit is disable. For the over current protect circuit point the value is set 100A. when inverter output current measured by current transformer is higher than the reference value in U17-2 the STOP signal is activated. At the same time led DS56 lightens. Just like kV lower protect circuit this protect circuit is enable after a time of 6ms after giving the exposure command. For the DC bus error protect circuit point the value is set 250V and 360V. When DC bus voltage is lower than 250V or higher than 360V the exposure is disable. To the circuit, when DC bus voltage signal UDC is higher than reference value in U19-1 and U19-2 the STOP signal is activated. At the same time led DS8 lightens. Jumper W1 can disable this protect circuit. If jumper W1 is short circuit the higher protect circuit is disable. For the kV unbalance protect circuit point the value is set 10kV. When difference between +kV absolute value and –kV absolute value in the monoblock is higher than 10kV the exposure is disable. To the circuit when difference signal KVN is higher than the reference value in U18-2 the STOP signal is activated. At the same time led DS57 lightens. For the IGBT error protect, the driver IC U23, U24, U26, U27 can provide this functional circuit. When IGBT is short circuit those 4 IC will send out fault signal to disable exposure. All the protect threshold is as follows. kV lower protect circuit kV higher protect circuit Over current protect circuit IGBT error protect circuit DC bus error protect circuit kV unbalance protect circuit

LED OUTPUT KV control board provides LED output warning when protect circuit is activated. All warning state can be clear through pushing switch S1 or energizing the kV control board again. The IGBT board in the generator includes fuse F, IGBT Q1,Q2,Q3,Q4, snubber circuit (composed by R,C,D components) and common inductor L. The drive signal for IGBT is given by the kV control board. The IGBT board actually is a DC-AC inverter and the DC input of this board is the output of a AC-DC converter consisted by the main transformer, rectifier bridge and the DC bus capacitor. For the serial resonant frequency of resonant circuit is nearly 40kHz, the IGBT board provides 40KHz variable AC power to Monoblock. The Block diagram of the IGBT board is shown as follows:

Filament Driver Board

The filament transformer current sense circuitry uses hall current sensor to provide analog output proportional to the actual filament transformer current, the ratio between the filament current and transformer current is 1:3.5556. The FDB is mounted in the Mainframe E-box. It is responsible for several functions as follows: -

Provide PWM output for driving Filament Transformers in High Voltage Tank Switch large or small filament focus Stop PWM generation for a while delay when switching large or small filament Over current protection Provide the over current alarm signal to MCB Respond to alarm signal from MCB and stop PWM generation Filament transformer current closed loop control

The FDB consists of 9 function blocks: Inverter, Overcurrent protect, PWM control, Filament select circuit, Hall current detect, Filament transformer current control, L/S focus switch, 10V reference, and Interlock. Inverter The filament drive pulses PWMA and PWMB are applied to two triodes Q3 and Q5 to drive power MOSFET Q4 and Q6 in a switching stage. When either input is high, one of the two MOSFET’s gates is positive and the other negative. Power to the switching stage is constant +24V, needed 1.4A power input, which is provided from external switching power PS1. Overcurrent protection The filament current is monitored across a 0.255Ω, comprising R4 and R5 in parallel, in the DC bus. The sample voltage inputs to Q1 base. The filament current for the large focus is less than 1.4A in normal condition, which yields less than 357mV across the resistor pair. When the filament current exceeds 2.75A, the voltage will exceeds 0.7V, Q1 will drive the base of Q2 on, then Q2 collector will be grounded, OCALM_FDB will go high, OC_ALM_S will go low to drive U3(1/4) on to pull SMAC to -15V, SG3525 output will shut down until S1 is pressed or the system restarts. Inductor L1 limits the peak switching current through transitions and reduces high frequency radiated energy from the output stage.

PWM control Pulses PWMA and PWMB at a frequency of 600Hz are produced by SG3525, pulse width modulator control integrated circuits. The deadtime is programmed by C2 and R16. The duty ratio is controlled by regulating circuit of MAC_FDB from MCB that is current setting by the preheat table lookup and feedback filament current value that is provided by hall current sensor. The FILDIS_FDB from MCB can shut down SG3525 outputs directly. Filament select circuit The filament selection is made by applying logic high to FCSSW_FDB. This turns on Q7 and operates relay K1. Under these conditions, the large filament is selected and LED HL3 lights. The filament drive outputs FILLA1 and FILLA2 are connected to the large filament primary side. The FILSM1 and FILSM2 are connected to the small filament primary side. The FCSSW_FDB line will be pulled low by a resistor R28 if the connection is broken. Hall current detect The FILCOM are connected to the central tap of the two primary sides of filament transformer in high voltage tank. The return filament current passes through FILCOM to 24V_GND. If the filament current via the hall current sensor CSNE151 is 5A, the current through Pin.13 of CSNE151 will be 25mA, which is a RMS value, the voltage on TP1 will be 2.5V. The analog signal goes through RC filter composed of R10 and C4 to filament current regulator. Filament current control The FCSSW_FDB determines the scale factors of regulating circuit towards MAC_FDB when the filament is selected. Subtracting return filament current value LEMF from MAC_FDB through different scale operation circuit, the result is sent to SG3525 to control duty ratio. Normally, MAC_FDB is less than 5V, more than 3V. IF MAC_FDB is much more than 5V, filament current will be maximized and SMAC will exceed 3.3V of input threshold of PWM comparator of SG3525, Duty cycle will be maximized, FWMC_FDB will be send out to MCB until disposed. Both of the delay circuit and the signal FILDIS_FDB from MCB are able to drive U3(2/4) on to pull SMAC to 15V, and OC_ALM_S is able to drive U3(1/4) on to pull SMAC to -15V, SG3525 outputs will shut down. L/S focus switch When filament focus switches, PWM pulses will shut down for a while delay of 56mS, because operate time of relay is about 7mS and RC circuit of coil of relay costs about 6mS. The delay time should be more than 13mS. The delay signal is produced by CD4538 and logic gates. The delay time is determined by R42, C29 and R41, C28. 10V reference The U7 REF102 chip provides standard +10V for regulating circuit. Interlock The J1A-13 and J1C-13 pin of connector are connected as interlock. The interlock goes through the FDB to verify that the FDB is in place.

Monoblock

Monoblock can generate X-ray. It mainly consists of high voltage generator and tube insert. All high voltage components are put into oil box, which can enhance the insulation performance. Monoblock generates 110kV inside the oil tank. The input voltage changes from 0V to 240V peak value. High voltage is got from high frequency and high voltage transformer T1. The primary coil is 10T and the secondary coil is 2500T. So the maximum voltage of secondary side is 60kV peak value at 40kHz. Monoblock Schematic Diagram: T1 D1

T3

High voltage circuit comprises rectifier circuit and voltage doubler. High voltage circuit composes of high voltage diode D1-D4, high voltage capacitor C1-C4. If output voltage from T1 is 60kV peak value the high voltage circuit output 120kV to the tube. The controller needs to get kV value and mA value from monoblock. KV sense circuit comprises high voltage resistor R1, R4 and sense resistor R2, R3. The high voltage resistor value is 400M ohm, sense resistor is 20k ohm If the voltage on the tube is 120kV the +kV output 3V and –kV output –3V. mA value is measured by serial resistor between –mA and ground. So the mA voltage value is negative. The tube is used to generate X-ray. This tube is a kind of double focus with fixed copper anode tube. It is suitable for oil insulation generator. Analog signals KV_GND and MA_CAT of sealing board are the anode and cathode of mA current signal respectively. There are two temperature measurement circuits in sealing board. One’s output is analog signal OIL_TEMP. The other’s output is connected/open status between THERMAL_SWITCH_A and THERMAL_SWITCH_B. If the temperature of oil tank is higher than a preset threshold, the relationship between THERMAL_SWITCH_A and THERMAL_SWITCH_B changes from connected to open.

Image Chain

Overview The following diagram is the image chain pipeline of Brivo715/785/865.

Collimator collimates the X-ray beam to the appropriate field size and user’s setting. The x-ray beam passes through Grid to reduce scattered X-ray photons. Image Intensifier converts this X-ray into lights for each field size selection, and sends the light to CCD Camera head. CCD Camera head captures the light image and sends the digital video data by Gigabit LAN to Network card. Network card input digital video to CPU, and the CPU performs real-time post-processing (Brightness, Contrast, Edge Enhance, Zoom, and Negate) to be sent to image display. CPU also analyzes the digital video signal, and outputs a video level indicator (VLI) to MCB; higher VLI when the Xray dose is higher than desired, and lower VLI when the X-ray dose is lower than desired. With AutoTechnique enabled, VLI will be processed by MCB S/W, and commands will be sent to X-ray Generator and GigE Camera to change kVp/mA/gain depending on the VLI value. Finally the optimized image and exposure technique are produced.

Collimator Control Collimator: The collimator is an electromechanical assembly designed to allow the operator to restrict the size and shape of the X-ray beam. The unit has a lead iris and shutters and is mounted directly over the X-ray tube beam aperture. There are 3 motions in collimator: iris open/close; shutter open/close; shutter rotation. -

The diameter of the iris aperture The gap spacing between the semi-transparent copper leaves The rotational position/orientation of the copper leaves

Collimator specification: -

Length×Width×Height: 180 mm×130 mm×95 mm Weight: 1.65kg 8 leaves motorized iris collimator 2 blades motorized shutter Shutter rotate angle: 360 degree

Collimator Control: Overview Collimator control subsystem is responsible for collimator motion control and status feedback. It consists of Mother Board/MCB/CCB/collimator/cables between them and firmware in MCB.

2-62

System Overview

There is an independent control loop working for each motion. The negative feedback control loop is used. E.g. for iris control, the following steps will be operated: a)

Firmware in MCB sends a command to CCB by SPI bus to tell the required position of iris.

b)

CCB receives the command and compares it with the feedback position signal coming from the Collimator. A PI operation is performed and works out the control signal. The signal is converted to drive voltage by a power amplifier and sends to collimator.

c)

The drive voltage drives iris motor moving and the position feedback will be closer to command. So the difference between command and feedback will reduce. The drive voltage returns almost zero while the feedback is very close to the command. The control loop is finished.

Collimator control subsystem works in following situations. a)

Move the iris and shutter to default position for each Mag mode. The default position is sent to Collimator Control Board in one command.

b)

Move the iris and shutter to default position for film mode and return to last position while recovering from the film mode. The default or last positions is sent to CCB in one command.

c)

Follow the operation of collimator from control panel. And the initial collimator position in each Mag is the calculated result in collimator calibration recorded by system.

Take the image and pack them per GigE protocol



Output Image per LIH control



Output Frame Synchronization Signal



As previously being mentioned, two kinds of camera share common electrical part. Following picture shows the structure of electrical function. Camera System Control

In this structure, FPGA is central control unit of GigE Camera. FPGA controls CCD driver electrical circuit to drive CCD sensor, then CCD sensor transfers the optical signal into analog signal. VGA and 12-bit ADC convert analog signal to digital signal. FPGA buffers digital signal into image buffer, then output per GigE Vision protocol. FPGA can adjust the gain of image per receiving external gain control command from RS422 serial port. FPGA provides two GPIO signal. One is FrameSync output, the others is LIH input. FPGA makes FrameSync signal low for 5ms then high at every frame according 25FPS. FPGA uses LIH signal to control transmitting of image as following: after 2 ms on the every falling edge of FrameSync, FPGA starts to check LIH. If LIH is continuous high for 10 ms, FPGA start to transmit image. Otherwise, FPGA stops transmitting. GigE Camera receives +12V DC as power input then converts different DC voltage to supply different circuits. Interface There are two connectors in GigE camera. One is industrial standard RJ-45 connector for GigE Vision Protocol on Gigabit Ethernet, IP: 192.168.42.239. The other is HDB15 female connector which provides power, RS422 and GPIO as following Table: Pin 1 2 3 4 5 6 7

Motorized Mechanical Operation The Vertical Column is motorized and should be observed continuously during operation to avoid pinching or colliding with people and object. If covers are removed, use extreme care when operating motorized features. Do not carelessly place objects on the equipment or bump or lean against the equipment. Do not wear loose clothing that may be caught by mechanical mechanisms. Keep hands and fingers clear of motorized equipment while the motors are in operation. Electrical Shock WARNING

WARNING

8-2

This system can generate lethal voltages. Practice safe electrical testing procedures when performing periodic maintenance procedures. After taking X-rays, the high voltage cables can retain a lethal charge, even if you power down the system. Even though the contacts are recessed, high voltages can arc several inches from their terminals if the cables are removed from the connector wells. Use caution when disconnecting high voltage cables even when the power is turned off. If you remove these connections, immediately discharge their contacts against the high voltage tank case (ground).

Periodic Maintenance

X-radiation Exposure The X-ray tube assembly produces X-radiation when energized. Never operate this device without X-ray shielding in place. Use lead shielding and draping to protect personnel. WARNING

Lead aprons, radiation monitors, and appropriate radiation shields must be utilized for the protection of all personnel in the vicinity while performing tests. Living human anatomy should never be used as a phantom or demonstration aid. Do not produce radiation in hallways.
