Filed: 1984-01-31
Abstract: PURPOSE:To obtain a picture with no irregularities over the whole area by changing a current in an X-ray tube in accordance with the control signal which changes with time from the original value along the set path and by maintaining the quantity of X-rays reaching the surface of a film at a constant level. CONSTITUTION:When the irradiation of X-rays is started, an irradiation switch 28 is turned off. Then the integrating circuit starts its function of integration and the integrated voltage gets higher gradually. In the adding circuit, this integrated voltage is added to the output voltage from a buffer, and the adding circuit outputs the voltage which gets higher gradually than the original value with time, being sent to a comparison circuit 17 as the control signal. On the other hand, the filament voltage is detected by a voltage detection circuit 16, and this detected voltage and the above-mentioned control signal are compared in the comparison circuit 17 and the resultant difference is sent to a drive circuit 14. In this way, a transistor 13 is controlled so that there may be no such difference as stated above, and the tube current can be changed in accordance with the control signal.
