Abstract
In an X-ray tube arrangement of the kind in which an electron beam is deflected along a target/anode there is provided means for monitoring the progress of the deflection to correct for errors. Detectors are provided to receive radiation from the regions of intended reversals in the scan. By monitoring maxima and minima in the waveform from those detectors the true position of the reversals can be estimated.
