X-ray imaging device

Abstract

Abstract PURPOSE:To compare an actual X-ray stop amount displayed on a monitor with an open amount by providing a display displaying the open amount of the stop detected by a video signal. CONSTITUTION:The image of a piclture picked up by a video camera 8 is converted into a video signal by a video camera controller 15, where the signal is divided into two; one is applied to a monitor 9 and the other is fed to a camera controller 14. Then, the camra controller 14 detects the shadow of the X-ray stop, operates to what degree in size the shadow corresponds on a camera 10 to control the aperture stop of the camera 10. The amount of the shadow or the amount other than the shadow is displayed on a display device 16. The actual X-ray stop amount displayed on the monitor is checked by displaying the stop opening amount on the display device in this way.
