ABSTRACT:
A rotary anode type X-ray apparatus includes an arithmetic unit for calculating the optimum number of revolutions of the anode, on the basis of the previously measured and stored temperature-characteristic data of the X-ray tube, at least one of the tube voltages applied to the X-ray tube, the X-ray radiation time, and the tube current. According to frequency of revolution data derived from the arithmetic unit, the motor controller drives the motor to rotate the rotary anode at an appropriate number of revolutions. This number is determined by the X-ray tube drive conditions, including the tube current.
