Abstract

A method has been developed to noninvasively measure the instantaneous potential (kV) applied to an x-ray tube. The method uses differentially filtered x-ray detectors whose outputs during the exposure are converted to digital signals and stored in a memory array. The conversions are made every 125 microseconds. After the exposure, a microprocessor calculates the ratios of the detector outputs; computes the kV waveform from stored calibration data; and digitally displays the kV value. A resolution of ±0.5 kV at 110 kV has been achieved.
