WebPeak kilovoltage ( kVp) refers to the maximum high voltage applied across an X-ray tube to produce the X-rays. During X-ray generation, surface electrons are released from a … WebKilovoltage potential (kVp) is the highest potential voltage achieved at any given kV setting. Higher kV settings produce more penetrating beams in which a higher percentage of the x-rays produced penetrate the subject being radiographed. There is also a decrease in the percentage difference in absorption between tissue types.
