WebMar 7, 2024 · Computed radiography (CR) is the use of photostimulable phosphor as an image receptor. The image receptor is held in a similar casing (cassette) to that of the traditional film screen. Computed radiography harnesses the absorption of radiation, trapping electrons at energy levels via the process of photostimulable luminescence. WebJun 22, 2024 · Each digital image system provides an Exposure Index (EI), a target EI, and the deviations from that target EI 3,4. The EI is a numerical value related to the signal to noise ratio squared of an image, a marker for exposure quality. Each examination has a target EI, values under that EI are considered underexposed, values above, overexposed 3,4. flood light iec standard
