WebImage quality assessment with dose reduction using high kVp and additional filtration for abdominal digital radiography Dose reduction for abdominal digital radiography can be achieved with comparable image quality by performing abdominal digital radiography using 92 kVp with 0.1-mm copper filtration, despite the higher AEC dose. 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. fnaf special delivery free
