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. Web16 de set. de 2016 · The high kVp beam can effectively penetrate metal objects and avoid photon starvation. That information can be used to help reconstruct the low kVp data. To incorporate the high-kVp assisted CT information, two kinds of MAR methods are proposed: dual-energy normalized MAR (DNMAR) and high-energy embedded MAR (HEMAR).
