X-ray image intensifier device provided with a circuit to compensate for magnetic distortion effects

摘要

in order to compensate for the effects of magnetic distortion in an image intensifier tube (1) radiation (18) is changed, the scanning mode of the target (7) of the camera (8) coupled to the tube. it is time (h, v) of the scanning line and the corresponding vertical scanning distortion measured (20 - 24).in this way, it renders on a display screen (30) for use in an image morphometry.
