Final answer:
The process described is called computed radiography, where radiation is used to create a detailed two-dimensional image via a process that includes capturing multiple X-ray images and computer processing.
Step-by-step explanation:
The process by which a photostimulable luminescent plate is exposed to radiation and converted into a high-quality two-dimensional image is called computed radiography. In computed tomography (CT), also known as computed axial tomography (CAT), X-rays are used to create detailed images of the body. A CT scanner rotates around the patient, taking X-ray images from different angles, which are then processed by a computer to produce a two-dimensional view of a 'slice' of the patient's body. This allows for a much more detailed view compared to standard X-rays, which provide only a two-dimensional view. Techniques like SPECT and PET also utilize nuclear activity to form detailed three-dimensional images, providing additional data for medical analysis.
