What component stores the image of the body part in digital radiography?

The component that stores the image of the body part in digital radiography is the photostimulable storage phosphor (PSP). In digital radiography, when exposed to X-rays, the PSP captures the energy and stores it in a form that can later be retrieved and converted into a digital image. This process involves the photostimulable phosphor layer in the PSP which absorbs the energy from the X-ray exposure and retains it until it is stimulated by a laser in a reader unit, which then produces a visible image.

Other components, like image receptors and digital sensors, also play key roles in capturing and converting the X-ray data, but they typically refer to the systems used to capture the image rather than the specific storage mechanism inherent to PSP technology. Film strips, while used in traditional radiography, do not relate to digital systems where PSP plays a crucial role in image storage and processing.
