A high resolution system to supplement intermittent image fields in X-ray television monitoring for diagnosis, in which X-rays are radiated intermittently for every one or several frames of television signals, a field of video signals obtained in each X-ray radiation is recorded, and a signal thus recorded is repeatedly reproduced to obtain, through a delay circuit, two pieces of the video signal with a phase difference of one half of a horizontal scanning period, so that, by combining these two pieces of the video signal and displaying them as a frame of images, an image of high resolution can be observed even during the periods of interruption of X-ray radiation.
