The higher the energy, the more photons will penetrate the body, the less that are absorbed. Although this reduces patient dose, image quality is compromised due to reduced contrast of a preferentially forward scattered radiation [2], [3].

WebIntroduction: High kVp techniques, 15% or 10-kVp rules, are well-known dose reduction methods. Traditionally, the use of high tube potential (i.e. increased kVp) is associated with decreased radiographic contrast and overall image quality. Recent studies suggest contrast and image quality are not heavily reliant on kVp with digital systems. 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 heated cathode by thermionic emission.

Web27 de fev. de 2016 · In addition, whenever a 15% change is made in the kVp to maintain the exposure to the IR, the radiographer must adjust the mAs by a factor of 2. Remember that a 15% change in kVp does not produce the same effect across the entire range of kVp used in radiography. A greater increase is needed for high kVp (90 and above) than for low …
