Abstract

PURPOSE:To always ensure the recording and storage of the video signals of a constant amount with no effect given by the delay of the rise, by securing the control so that the X-ray dose entering the image intensifier may be constant. CONSTITUTION:The X-ray irradiation switch 31 is turned on to send X-ray irradiation starting signal V1 to high voltage device 11. Thus the X-rays are irradiated via X-ray tube 12, and the X-rays passed through subject 13 give the light emission to image intensifier 14. And this output is detected by photoelectric tube 19. When the integrated value of the optical current reaches the fixed level, phototimer control circuit 20 transmits X-ray cutoff signal V2. Thus switch 32 is opened to discontinue the X-ray irradiation and controlled in order to secure the constant irradiation of the X-rays at all times. With generation of signal V2, switch 33 is turned on, and video recorder 17 performs the record storing action via the recording signal of a fixed time through recording time setting circuit 22. When the recording period is over, recorder 17 stops the recording of the video signal and starts immediately the reading of the stored video signals for display on TV monitor 18.
