Quantitative Measurements of X-Ray Intensity

WebJun 9, 2024 · Particularly in larger body parts, such as obese adult torsos, lower energy photons are absorbed completely without contributing to image formation. In such situations, higher kVp is employed to improve the x-ray intensity reaching the receptor, thus increasing the signal to noise ratio on the images. WebJan 30, 2024 · The intensity of X-ray fluorescence is directly proportional to the X-ray absorption cross-section of the sample. However, in practice as a beam of X-ray is shined on a sample, a variety of X-rays are emitted, they can be fluorescent X-ray from the sample and background X-ray from the sample scattering.
