A CR reader is a device used to read and interpret data from CR (computed radiography) systems. These systems capture images using special imaging plates that store X-ray data. The CR reader processes these plates, converting the stored information into digital images for medical analysis. The primary use of a CR reader is in the field of radiology, where it helps healthcare professionals diagnose conditions by providing clear images of the body's internal structures. This technology enhances the efficiency of medical imaging, allowing for quicker diagnosis and treatment planning.
