Abstract

PURPOSE:To make it possible to observe clearly the moving image of an object by a TV, by detecting the intensity difference of tomographic videos different by time and by superposing it onto the tomographic video signal to emphasize and display the moving part in tomographic X-ray video. CONSTITUTION:The X-ray permeating image of object 1 is made into a bright visible image by X-ray video amplifier tube 2 and is photographed by camera 3. The video signal from TV camera 3 is distributed to video memory unit 4, differential amplifier 6, and signal synthesizer 7. The video signal delayed by video memory unit 4 is input to differential amplifier 6, and the intensity difference between this video signal and the video signal from TV camera 3 is detected, and this difference signal and the video signal from TV camera 3 are input to signal synthesizer 7 and are synthesized, and the composite signal is input to monitor TV 8.
