What does kVp stand for in X-ray terminology?

In the context of X-ray terminology, kVp stands for kilovolt peak. This term refers to the peak voltage applied across the X-ray tube during the exposure, which determines the energy and penetrating power of the X-ray beam. A higher kVp setting increases the energy of the X-rays produced, which allows for deeper penetration of tissues and improved image quality, especially for thicker body parts.

Understanding kVp is essential for radiologic technologists as it directly affects contrast and overall image quality. The concept of kVp highlights the importance of adjusting this parameter based on the specific imaging requirements, such as the type of tissue being imaged and the diagnostic purpose of the X-ray. This makes kVp a critical factor in achieving optimal imaging results in radiography and fluoroscopy.
