ABSTRACT:
In an X-ray imaging apparatus, unwanted electron charges caused by pulsatory X-ray trailing edges are eliminated from an X-ray image signal of a biological body under medical examination. The X-ray imaging apparatus comprises: an X-ray generator for generating a plurality of pulsatory X-ray beams; an X-ray controlling unit for supplying an X-ray projection controlling signal to the X-ray generator in order to project an X-ray pulse beam having a predetermined pulse width to a biological body under medical examination from the X-ray generator, thereby producing an X-ray image of the biological body under medical examination; an optical converter for converting the X-ray image into a corresponding optical X-ray image signal of the biological body under medical examination; an imaging unit for imaging the optical X-ray image signal derived from the optical converter to store the imaged optical X-ray image signal as electron charges therein; a driving unit for driving the imaging unit in such a manner that only electron charges produced while projecting the X-ray pulse having the predetermined pulse width to the biological body in response to the X-ray projection controlling signal, are read out as an effective X-ray image signal of the biological body under medical examination; and, a display unit for displaying thereon an effective X-ray image of the biological body under medical examination in response to the effective X-ray image signal.
