Gamma cameras the most widespread of nuclear medical diagnostics. How does a gamma camera work?introductory animation explaining the functions of the main components of the gamma camera:
Gamma Camera Diagram. Single photons are emitted from a subject, and due to the collimation, only photons that run perpendicular to. The diameter is dependent on the application of the device.

A crystal inside the head of a gamma camera scintillates in response to radioactive particles, producing a burst of light that is picked up by sensors located behind the crystal. How a gamma camera works a sodium iodide crystal gives a tiny flash when a gamma photon hits it. Block diagram of a gamma camera the crystal and pm tubes are housed in a cylindrical shaped housing commonly called the camera head.

Gamma cameras or scintillation cameras are pieces of apparatus which allow radiologists to carry out �scintigraphy scans�, tests which provide detailed diagnoses about the functioning of the thyroid, the heart, the lungs and many other parts of the body. Gamma camera scan of kidneys the electrical output can be translated into colour coded graphical display using electronic circuitry. For example a 25 cm diameter crystal might be used for a camera designed for cardiac. To detect the gamma photons we use a large crystal of sodium iodide.
