In fluoroscopy, kilovoltage peak (kVp) typically ranges from 60 to 120 kVp, depending on the exam being performed. Lower kVp settings are usually used for pediatric patients and higher kVp settings for larger patients or exams requiring more penetration.
An increase in kVp by 15% must be accompanied by a reduction in mAs by 50% in order to maintain radiographic density. Inversely, a reduction of 15% in kVp must be accompanied by an increase in mAs by a factor of 2 (Doubling).
kvp- peak kilovoltage controls the radiographic contrast of an x-ray image. on some x-ray machines (older ones) the kvp's have to be manually set according to the measurements of the subject being x-rayed, in order for the x-ray to come out right.
kVp is the penetrating ability of an x-ray and half value layer is the amount of filtration or thickness of an object needed to reduce the intensity of the x-ray by half. So if you decreased kVp, then the half value layer would decrease.
Kilovolt peak (kVp) controls the quality of x-rays by determining their energy and penetrating power. Higher kVp settings produce x-rays with greater energy, which can penetrate thicker or denser materials, resulting in improved image contrast and clarity. Conversely, lower kVp settings yield lower energy x-rays, which may be insufficient for penetrating certain tissues, leading to images with poor detail and increased radiation dose. Thus, optimizing kVp is crucial for achieving high-quality diagnostic images while minimizing patient exposure.

To convert kiloelectronvolts (keV) to kilovolt peak (kVp), you can use the fact that 1 keV is equivalent to 1,000 electronvolts. Since kVp represents the peak voltage applied in kilovolts, you typically don't convert directly between the two units, as they measure different concepts. However, in certain contexts, such as X-ray production, you can consider that kVp settings influence the energy of emitted X-rays, which are often measured in keV. To get a rough conversion, you might consider that 1 kVp can produce X-rays with energies up to approximately the same number in keV, but the relationship is not a direct conversion.
The main difference between keV and kVp in radiography is that keV refers to the energy of the X-ray photons used to create the image, while kVp refers to the peak voltage applied to the X-ray tube. Adjusting keV affects image contrast and sharpness, while adjusting kVp affects overall image brightness and penetration. Both factors play a crucial role in determining the quality of the radiographic image.
