Detailed explanation-1: -Increasing kVp increases the penetrating power of the x-ray beam. If kVp is too low, the image will lack density resulting in a whitewashed or sooty appearance. If kVp is too high the image will be over exposed and too dark.

Detailed explanation-2: -* kVp: the power and strength of the x-ray beam (quality of the x-rays). * mAs: the number of x-ray photons produced by the x-ray tube at the setting selected (quantity of x-rays). * time: how long the exposure lasts.

Detailed explanation-3: -Image quality Particularly in larger body parts, such as obese adult torsos, lower energy photons are absorbed completely without contributing to image formation. In such situations, higher kVp is employed to improve the x-ray intensity reaching the receptor, thus increasing the signal to noise ratio on the images.

Detailed explanation-4: -An increased ratio of Compton scatter introduces excess photons that reach the image receptor. As a result, the image becomes overexposed. To achieve the best possible results, kVp is increased for sufficient exposure but kept low to minimize overexposure and radiation dose.
