X-ray image intensifier tube with circuit to compensate for the effects fo magnetic distortion

摘要

To compensate for the effects of magnetic distortion in an X- ray image intensifier tube, the mode of scanning the target of the television camera associated with this tube is modified. Shifts, corresponding to measured distortions, are caused in the line scan and the vertical scan. In this way, an image which can be used in morphometry is restored on a display screen.
