ABSTRACT:
An X-ray diagnostic apparatus comprises an X-ray tube, a fluorescent plate for converting X-rays transmitted through an object irradiated with X-rays from the X-ray tube into visible light rays, a light image intensifier for intensifying the visible light rays, an image sensor for sensing an image contained in the output light rays from the intensifier and converting it into video signals, image processing unit for image-processing the output signals from the image sensor to intensify the image and to add together the image-processed video signals of a plurality of frames, and a monitor for visualizing the output signal from the image processing unit, where the video signals after image-processing are added together to increase the amplitude of the video signal.
