Changes

In diagnostic radiology, x rays, produced by machines, are transmitted through the patient’s body and detected by a receptor (or detection) system to generate the required image of the organs under investigation. The differential absorption of x rays in tissues and organs, owing to their atomic composition, is the basis for the various imaging methods used in diagnostic radiology. Modern diagnostic radiology uses a digital process for image acquisition, transfer, process and storage. Over the past years, with the tremendous technological progress and collaborative efforts in radiation protection, the radiation doses used in diagnostic radiology have been significantly reduced and continue to be reduced through technological innovations especially in CT (<ref name="Pub135">[[ICRP Publication 135]] Diagnostic Reference Levels in Medical Imaging; .
