In fluoroscopy, kilovoltage peak (kVp) typically ranges from 60 to 120 kVp, depending on the exam being performed. Lower kVp settings are usually used for pediatric patients and higher kVp settings for larger patients or exams requiring more penetration.
kvp calculation 6cm*2+40=?
An increase in kVp by 15% must be accompanied by a reduction in mAs by 50% in order to maintain radiographic density. Inversely, a reduction of 15% in kVp must be accompanied by an increase in mAs by a factor of 2 (Doubling).
Rearranging the the equation to make c the subject:- c = kVp-2t
kvp- peak kilovoltage controls the radiographic contrast of an x-ray image. on some x-ray machines (older ones) the kvp's have to be manually set according to the measurements of the subject being x-rayed, in order for the x-ray to come out right.

No, photoelectric absorption decreases with increasing photon energy (kVp). This is because higher-energy photons are more likely to be transmitted through the material or undergo Compton scattering rather than being absorbed through the photoelectric effect.
kVp should be increased by 15%
