What does kVp stand for in radiography?

In radiography, kVp stands for "kilovolt peak." This term is crucial in understanding how the x-ray machine operates. The kVp setting controls the maximum voltage applied across the x-ray tube, which affects the quality, penetration, and intensity of the x-ray beam produced. Higher kVp values result in more energetic x-rays that can penetrate denser materials, which is essential for obtaining clear images of different body structures.

Understanding kVp is fundamental for radiographers as it influences image contrast and radiation dose to patients. By selecting the appropriate kVp, radiographers can optimize image quality while minimizing exposure to radiation. This makes the knowledge of kVp a critical aspect of safe and effective radiographic practice.
