Abstract
A rotary anode type X-ray tube is controlled by an X-ray emission control device. In the X-ray emission control device, the maximum permissible storage heat quantity which can be applied to the rotary anode of the X-ray tube is set, the anode storage heat quantity which is lowered based on the cooling characteristic of the rotary anode is calculated, the present anode storage heat quantity is calculated, and the imaginary anode storage heat quantity for the next X-ray emitting condition which is derived by calculation using the correction functions based on the anode input power, emission continuation time, anode rotation speed and focal point size, the anode input power of the next predicted X-ray emission, and X-ray emission continuation time is calculated. The maximum permissible storage heat quantity, the present anode storage heat quantity and the imaginary anode storage heat quantity in the next X-ray emitting condition are compared and calculated to determine permission or inhibition of the next X-ray emission. The performance of the mounted X-ray tube is fully utilized by use of the X-ray emission control device, the wait time to the next X-ray emission can always be suppressed to minimum, and the X-ray tube apparatus can be controlled with high speed and high reliability.
