Abstract
Due to the widespread use of high-speed rare-earth screen/film combinations and pulsed cine and digital radiography systems in radiology departments, the short exposure time performance of the x-ray generator is of increased importance to the production of high qual-ity images. For short exposures slow rise time of the high voltage applied to the x-ray tube may result in the peak tube potential differing significantly from that indicated. Similarly, a pulse overshoot on the leading edge of the high voltage waveform may produce a peak tube potential greater than that indicated. The measured high voltage and current waveforms of three-phase generators representative of the major x-ray equipment manufacturers are presented as a function of tube potential, tube current, and exposure time. The implications of the results are discussed, and a comprehensive definition of generator minimum exposure time is proposed.
