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.
The strength of an xray is refered to as kVp, and it varies depending on the speed of the electrons before they hit the anode inside the x-ray tube.

The exposure factors control the amount of radiation emitted from the x-ray tube. These factors include tube current (mA), tube voltage (kVp), and exposure time (seconds). Adjusting these parameters can alter the amount of radiation produced in the x-ray tube.
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
Four primary aspect of exposure: mA: controls density - overall blackness of image kVp: controls contrast Exposure time: how long the exposure lasts Distance (SID) : source distance - how far away the body part is from the primary beam
kVp is the penetrating ability of an x-ray and half value layer is the amount of filtration or thickness of an object needed to reduce the intensity of the x-ray by half. So if you decreased kVp, then the half value layer would decrease.
