Abstract

A diagnostic X-ray apparatus includes an X-ray tube, an image intensifier for converting an X-ray image of an object under examination to an optical image, a solid state image sensor device for detecting the optical images produced by the image intensifier and converting the optical means into a series of video signals, a CCD driver generating field shift pulses for driving the solid state image sensor device at a predetermined rate, pulse width determining means for determining a pulse width of the X-ray pulses, and X-ray control means for controlling an emission period and timing of the X-ray pulse emitted from the X-ray tube. In the case that the solid state image sensor device performs interlaced scanning in a field storage mode, commencing with the second frame when the field shift pulse is generated by the CCD driver, the X-ray pulse continues to be emitted from the X-ray tube for a half of the pulse width determined by the pulse width determining means in the first frame. In case that the solid state image sensor device performs interlaced scanning in a frame storage mode, X-ray pulses having a pulse width determined by the pulse width determining means are emitted in the same field of each frame.
