The X-ray-taking process starts with the normal X-ray citation and the patient and X-ray cassette arranged in the usual positions. The loss is that the cassette contains a reusable phosphor plate, which is sensitive to X-rays but not light. erst the plate has been exposed it is fed into a laser figurer reader, which captures the delineation in a digital format. The reader past resets the plate ready for reuse.
The phosphor plates are expensive but can be reused several thousand cadences; they are also more X-ray-sensitive than film, allowing a slightly lower radiation dose to be used. The advantages of this process over silver-film developing are the expulsion of the expensive film, the absence of toxic developing chemicals and the speed. Within 30 seconds the image is visible, so if the image needs to be reiterate for technical reasons this can be done immediately.
With the advances in image quality and post-processing achieved by CR, radiologic technologists can compensate for exposure proficiency inaccuracies by adjusting the technique during the post-processing phase of the images rather than at the time of exposure. This is a disadvantage as it can encourage complacency rather than accuracy with exposure techniques, which can result in overexposed or underexposed images.
