WebGamma rays are a form of light that moves at a different wavelength than visible light. The cameras are mounted on a rotating gantry that allows the detectors to be moved in a tight circle around a patient who is lying … WebGamma cameras are commonly used in nuclear medicine procedures to visualize the heart, brain, thyroid gland, and other organs and tissues. They are also used to evaluate blood flow and to diagnose conditions such as heart disease, cancer, and infections. These images are useful to diagnose the disease or to know the function of various organs.
