1 Kilovolt Peak (kVp) kVp determine the quality of the beam. X-ray penetration is governed by the kVp setting. kVp controls the contrast of the radiographic image. Contrast is the difference in density of adjacent structures on the image.

2 Kilovolt Peak (kVp) kVp and the density of the body part impacts the amount of scatter radiation. High kVp = more scatter = low contrast = more penetration Low kVp = less scatter = high contrast = less penetration

3 Kilovolt Peak (kVp) Optimum kVp = consistent scatter = adequate contrast = sufficient penetration Optimum kVp is based upon the area of the body and film size to assure adequate penetration.

4 Technique Selection Adjusting kVp and mAs is a balancing act. When kVp is increased, mAs must be decreased. We are balancing both density and contrast of the image.

5 kVp Adjustment If kVp is increased without reducing the mAs, penetration increases and contrast is reduced.
