What does kVp stand for in radiography?

In radiography, kVp stands for kilovoltage peak. This term refers to the maximum voltage applied across the x-ray tube during the production of x-rays, which is crucial for determining the quality and penetrating power of the x-ray beam. The kilovoltage peak directly affects the contrast and the intensity of the imaging results. A higher kVp generally results in greater penetration capability of the x-rays, allowing for better imaging of denser tissues or structures.

Understanding kVp is essential for radiographers because it influences various aspects of image quality, such as contrast and exposure. Proper selection of kVp helps ensure that the resulting images are diagnostically useful while minimizing patient exposure to radiation.

Other terms listed, like kilovolt protection, kilovolt potential, and kilovolt phase, do not accurately describe the concept related to radiographic imaging, making "kilovoltage peak" the correct and most appropriate choice in this context.
