Phosphor imaging principle

WebThe phosphor transforms the X-ray image into a light image, which creates a latent image in the photographic film. The first step in making the X-ray image is to expose the screen/film sandwich in a light-tight cassette to the X-ray beam that has passed through the patient. WebJan 15, 2003 · Phosphor imaging is a type of digital autoradiography that has been widely used in biochemistry to examine radioactively tagged proteins. We used phosphor imaging to map in situ U and Th in polished slabs of geological materials including carbonates, phosphates, and silicate-rich rocks. We examined samples containing between 2 and …

WebApr 17, 2024 · A PSP imaging plate is typically made of a mixture of BaFBr and BaFI, activated with a small quantity of Eu (europium). When X-ray energy is absorbed by the phosphor, electrons associated with the europium atoms are excited and become mobile, and then a fraction of them will get trapped locally in a higher energy state. http://web.mit.edu/solab/Documents/Assets/So-2PF%20light%20microscopy.pdf
