Fig 1-1 COMPOSITION OF THE HFG AC input voltage is converted into DC voltage by a single-phase all wave rectifier circuit. This DC voltage is inverted in high-frequency voltage of about 20kHz by IGBT inverter. The high-frequency voltage is converted into the 40 (+20kV/-20kV) to 125kV (+62.5kV/-62.5kV) DC high voltage by a high-voltage transformer and the multi-voltage rectifier circuit. This DC high voltage is supplied to an X-ray tube through a high-voltage cable, and PWM INV controls this X-ray tube voltage. Modulating the Filament voltage controls the tube current. . The operation panel can operate selection in each mode of operation and control, selection and setting of conditions. These operation conditions are transmitted by the communication system from OP-CONT to HTCONT. HT-CONT controls the output of a high-voltage generator according to the instructions from OP-CPU.

SECTION 2. INSTGALLATION AND OPERATION 2-1. Responsibility of Installer It is the responsibility of the installer to correctly install this collimator as instructed in this manual. The installer must certify that the X-ray equipment on which the housing assembly the collimator is installed is in compliance with KFDA regulations.

2-2. Electrical Supply Requirement It is imperative that a sufficient power is supplied to the collimator lamp to obtain the specified voltage under onload condition being measured at the lamp socket.

2-3. Installation Method The following instruction should be read and thoroughly understood attemption to installed collimator. It is assumed that all persons installing, adjusting and maintaining this collimator have the knowledge and experience necessary to achieve the objective outlined. 1. Unpacking Carefully unpacking the collimator and check each piece for visible damage incurred during shipment. Any damage should be referred to the agency that delivered the collimator. 2. Collimator mounting procedures Collimator mounting consists of removing the flange ring from the collimator, fastening the flange ring to the X-ray tube port bottom and then fastening the collimator to the flange ring assembly. a. Remove the flange ring (A) from the top of the collimator by remove the two installation plates of ring (C). b. Use the proper screw length to insure that the mounting screw engage at least 5 threads into the X-ray tube port bottom, or mounting, surface tapped holes if adaptor plate is used. c. Attach the flange ring assembly to the X-ray tube (or tube support) with mounting spacer (no supply) inserted between the ring and the X-ray tube support. d. Thread the side safety screw (B2) in about 6mm, leaving the flange screw (B1) flush with the inside of the ring. e. Lift the collimator up to the installed flange ring. f. While the supporting the collimator, thread the side safety screw (B1) in, then tighten both safety screw (B1 and B2). g. Check the installation thoroughly for correct and safe mounting.
