Web1 de out. de 2024 · The use of the high KVp technique can play an important role in reducing radiation dose without significant loss of image quality. Introduction Newborn … WebHigh voltages that reduce the image dynamic range are therefore used when performing diagnostic chest radiographs on dedicated imaging systems located within the radiology … 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. bins for toy shelves
