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.
Key value pairs (KVP) are a simple way to store data where each value is associated with a unique key. Key value encoding (KEV) is a method of encoding data where key value pairs are structured in a specific format for storage or transmission. The main difference is that KVP is a general concept for organizing data, while KEV is a specific implementation of that concept for encoding data.
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.

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.
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).
Rearranging the the equation to make c the subject:- c = kVp-2t
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.

To lower the kilovolt peak (kVp) and milliampere-seconds (mAs) for an X-ray, you can adjust the X-ray machine settings before the exposure. Lowering the kVp reduces the energy of the X-rays, resulting in less penetration and a softer image, which may be suitable for certain body parts. Similarly, decreasing the mAs reduces the quantity of X-rays produced, leading to a lighter image, which can help avoid overexposure. However, it's essential to balance these adjustments to maintain image quality and diagnostic value.
