Abstract
A pinhole camera forms an image of the optical focal spot of an x-ray tube on a radiation-electrical transducer comprising an intensifier foil and a matrix of photo-sensitive detectors. A processing circuit including an adjustable amplitude selector selects detector output signals for transmission to a video monitor. A calibrated measuring grid can be superimposed on the focal spot image on the monitor.
