Radiologic Technologist Exam 2025 – Ready, Set, Radiate Your Future!

Question: 1 / 400

In radiography, what does the abbreviation "kVp" stand for?

Kilovoltage peak

In radiography, "kVp" stands for kilovoltage peak. This term refers to the peak voltage applied across the X-ray tube, which is responsible for the production of X-rays. The kVp setting significantly influences the quality and quantity of the X-ray beam; specifically, it controls the energy of the X-rays produced. Higher kVp levels result in more penetrating X-rays, which are useful for imaging denser structures, while lower kVp levels produce softer X-rays that are better for imaging less dense tissues.

Understanding kVp is crucial for radiologic technologists, as it affects image contrast and patient dose. A proper kVp setting can enhance the distinction between different tissues in an image, which is essential for accurate diagnosis. Thus, knowing that kVp represents kilovoltage peak helps in optimizing X-ray techniques and improving patient care.
