What does kVp stand for in radiology?

In radiology, kVp stands for kilovolt peak, which refers to the peak voltage applied across the x-ray tube. This voltage is crucial because it determines the quality and penetrating power of the x-rays produced. A higher kVp results in x-rays with greater energy and penetration capability, which can effectively pass through denser tissues to create clearer images.

Understanding kVp is important for optimizing image quality and ensuring appropriate patient safety levels by controlling the amount of radiation exposure. While other terms related to voltage exist, in the context of radiology and the operation of x-ray machines, kilovolt peak is the standard terminology used. This standardization helps ensure consistency in practice and communication within the medical imaging community.
