What does kVp stand for in radiography?

Kilovolt peak, commonly abbreviated as kVp, is a critical term in radiography that refers to the maximum potential difference applied across the X-ray tube. This setting is essential because it directly influences the energy and quality of the X-rays produced. A higher kVp results in more penetrating X-rays, which can improve image quality and reduce patient dose by allowing for lower exposure times. Understanding kVp is vital for radiologic technologists as it plays a significant role in determining the contrast and detail of the radiographic images obtained.

In contrast, the other options do not accurately reflect the terminology used in radiography. Kilo voltage precision, key voltage potential, and kilo variable power do not relate to the established terminology or principles governing X-ray production and imaging, which is why they do not represent the correct concept.
