Abstract
PURPOSE: To obtain suitable luminance in a short time, by memorizing the tube voltage immediately before the interrupted tomogram is present to the integrator, and by applying the tube voltage memorized to the X-ray tube from first when the tomogram is restarted.
CONSTITUTION: When tomogram is started firms, the output of the adder 21 which is the voltage of the reference power supply 22 is compared with the compartor 23, gate pulse is developed from the gate circuit 24 based on this, turning on the controlled rectifiers 3 and 4. Thus, X-rays from the X-ray tube 8 is caused and if does is insufficient, the error signal from the differential amplifier 13 is fed to the integrator 16. Thus, the voltage of the adder 24 is increased having suitable luminance by increasing the tube voltage of the X-ray tube 8 and the integrator 16 memorizes this output voltage. Thus, after tomogram is interrupted by opening the contacts 15 and 25 and further by closing them for restarting, the rectifiers 3 and 4 starts trigger immediately and suitable luminance is instantly appeared on the X-ray tube 8.
