WebMay 15, 2024 · How does direct capture radiography work? Specialized Imaging Digital radiography, also known as direct digital radiography, uses x-ray–sensitive plates that directly capture data during the patient examination, immediately transferring it to a computer system without the use of an intermediate cassette as is the case with CR. WebGamma cameras are based on the detection of gamma rays emitted from radionuclides. Radionuclides can be ingested or injected into the body. The camera accumulates counts of gamma photons, which are detected by crystals in the camera. Just like an X-ray, the gamma camera will yield a two-dimensional projection of a three-dimensional object.
