High kvp
WebTools Peak 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 heated cathode by thermionic emission.

WebThe dynamic range of the image obtained at 50 kV was 160 (i.e., L = 2.2), whereas the dynamic range of the image obtained at 125 kV was markedly reduced to 50 (i.e., L = 1.7). In radiology, it is generally true that high x-ray tube voltages (i.e., increased photon energies) reduce the dynamic range in radiographic images, and vice versa. WebPurpose: Dose reduction using additional filters with high kilovoltage peak (kVp) for abdominal digital radiography has received much attention recently. We evaluated image …
