にしたことを特徴とするＸ線透視撮影装置。 When imaging a region of interest located by X-ray fluoroscopy on a film, a part of the output light of the X-ray image intensifier is taken out by a photo pickup and converted into an electrical signal,
In an X-ray fluoroscopic imaging device that sets the film density by controlling the X-ray exposure time based on this electric signal, a position display signal corresponding to the position of the photo pick-up is transmitted during X-ray fluoroscopy. An X-ray fluoroscopic imaging apparatus characterized in that the position of the photopic is displayed on an X-ray fluoroscopic imaging screen by superimposing it on a video signal.
