What device is used to accept and scan the CR plate in radiology?

The correct choice is A, as the CR Reader is specifically designed for handling Computed Radiography (CR) plates. These plates contain photostimulable phosphor, which captures the radiographic image when exposed to X-rays. Once the imaging process is complete, the CR plate is inserted into the CR Reader, which scans the plate with a laser beam. This laser excites the stored energy in the phosphors, causing them to emit light, which is then detected and converted into a digital image.

The other devices listed have very different functions in the radiographic process. A Radiation Meter measures the amount of radiation exposure in an environment but does not interact with the CR plates. A Film Processor is used for developing traditional film-based radiographs, which is not applicable to CR technology. The X-ray Tube is the source of X-ray production; while critical to the imaging process, it does not have a role in accepting or scanning the CR plate. Thus, the CR Reader is the appropriate device specific to the needs of digital imaging using CR technology.
