Digital recording and playback system for X-ray video signals

摘要

In medical image treating systems, especially when an X-ray image intensifier and TV camera are used, video signals composed of available video signals containing specified image information and unavailable video signals containing no such image information are output from the TV camera. Only the digital video signals of the converted digital video signals corresponding to the available video signals are treated and the digital video signals after treatment are recorded and reproduced with a recording device.
