Web2 jun. 2024 · A gamma camera is a piece of medical equipment that is capable of detecting gamma radiation. The radiation can be recorded on film or displayed on a monitor. These devices are used in medical imaging studies that are designed to show doctors what is happening inside a patient’s body.
WebIn a sense, the crystal acts as a wavelength shifter. It generates long wavelength radiation (visible and UV) from short wavelength radiation (gamma photons). Because the light output of a crystal depends on the energy of a gamma photon that interacts with it, a gamma camera can be used for energy-selective counting.
