Ｘ線テレビ輝度調整装置。 Image Intensifier I. The X-ray transmission image during fluoroscopy is
．． so that when the output image is displayed on the TV monitor as a TV video signal via the TV camera and camera control unit, the area of interest on the screen can be observed at a constant brightness.
The peak value of the video signal or the video brightness control signal IB in that area within the camera control unit.
In the IBS signal generation circuit that detects S and the X-ray television brightness automatic adjustment device that controls the X-ray conditions by feeding back this detection signal, control operations are performed using multiple regions of interest on the screen of the TV monitor. It is characterized by detecting IBS signals according to each area by means of a switch added to the panel.
X-ray television brightness adjustment device.
