The are five ways X-rays interact with matter. These “scattered” photons will create a random grayness on the image, reducing the contrast between body tissues, and making it difficult to read the image clearly. ![]() As part of the absorption, a second photon with less energy will be produced, flying off in a different direction than the photon that was absorbed. This effect is like holding up paper to a light to see the writing on the other side. This produces an image of dark and light on the X-ray film. When taking an X-ray, may incoming X-ray photons are absorbed by the bone, a high attenuation material, while other tissues absorb less. Whenever X-rays pass through matter, some of the x-ray photons will interact with the atoms of the matter. Also, kVp and mA should be adjusted to acquire better X-ray images through the use of a grid. and the direction of the X-ray, such as AP (anterior to posterior), PA, Lateral, Oblique etc., each grid specification should be different. The scatter radiation is also known as “Compton scatter radiation.” Depending on the purpose of radiograph such as chiropractic, veterinary, etc. With regard to grid specifications, the object that scatter radiation arises is thicker than 10cm. The basic purpose of X-ray grid use is to enhance the contrast and quality of the medial image by removing the scatter radiation. ![]() ExamVue 10″ x 12″ Glassless Substrate Wireless.
