What effect does increasing kilovolt peak (kVp) have on an X-ray image?

Increasing kilovolt peak (kVp) enhances the penetration ability of X-rays. When the kVp is raised, the overall energy of the X-rays is increased. This elevated energy allows the X-rays to penetrate through denser tissues and materials more effectively, resulting in a more comprehensive image that can demonstrate variations in tissue density.

This concept is foundational in radiography, as different tissues absorb X-rays to varying degrees. Higher kVp settings help to ensure that even denser tissues provide adequate exposure on the X-ray film or digital sensor, leading to clearer images that reflect anatomical structures more accurately. This is particularly important in imaging areas like the abdomen, where organs and structures vary significantly in density.

Understanding the relationship between kVp and penetration is critical for GXMO operators as it directly affects image quality and diagnostic value.
