Peak kilovolt (kVp) is a term used to describe the highest voltage point reached during an X-ray or radiographic examination. However, there are other terms that can be used interchangeably with peak kilovolt. These include maximum voltage, peak tube voltage, tube potential, and highest energy level. These terms refer to the same concept as peak kilovolt in that they all describe the highest voltage point reached during an X-ray or radiographic examination. Whether you call it peak kilovolt, maximum voltage, peak tube voltage, tube potential, or highest energy level, it is an essential component of X-ray technology that helps produce high-quality images for medical diagnoses.
