X-RAY TUBE CURRENT CONTROL WITH CONSTANT LOOP GAIN |
摘要 |
The tube current in an x-ray tube is controlled by a closed loop control circuit in which a tube current feedback signal is used to control x-ray tube filament current. The gain of the feedback loop is maintained substantially constant over a wide range of tube currents by inserting a signal proportional to the reciprocal of the tube current command.
