TīmeklisThe higher the kilovoltage setting, the higher the average energy of the x-rays. In the early days of radiology, there was a large difference between the maximum voltage and the average voltage across the tube, so a distinction was made between the peak kilovoltage (kVp) and the kilovoltage at any instant (kV). Tīmeklis2015. gada 12. marts · Exposures made at the same kVp and mA stations of the same phantom thickness should produce the same optical density on the resulting image. This is referred to as reproducibility (Papp, 2011, p. 107). This speaks to the fact that the radiation intensity produced by the x-ray tube should be the same given the same …

Tīmeklis2016. gada 6. marts · kVp and the 15% Rule. A 15% increase in kVp has the same effect on exposure to the IR as doubling the mAs. A 15% decrease in kVp has the same effect on exposure to the IR as decreasing the mAs by half. Increasing the kVp by 15% increases the exposure to the IR, unless the mAs is decreased. TīmeklisThe two major components of the 15% Rule are: 1) The number of x-ray photons incident on the patient is approximately ~kVp^2. 2) The likelihood of the x-rays to …

When the kVp increases, the number and energy of x-ray photons generated at the anode increase. This will result in a higher number of photons with higher energies reaching the receptor, and this leads to an overall increase of density of the radiographic image at a greater scale when increasing mA or exposure time …
