What is Gamma camera in Nuclear Medicine is used for: and explain in detail?
B i.e. Measuring the radioactivity A gamma camera, measures radioactivityQ of the substance that is taken up by specific organ or tissue of interest, by detecting gamma rays Working of gamma camera Nuclear medicine studies require the oral or intravenous introduction of very low level radioactive material (called radio pharmaceuticals, radionuclide or radiotracess) into the body; which is taken up by a paicular organ or tissue. The decay of radiotracer then leads to emission of y (gamma) rays, which are measured by gamma camera with the help of its crystal detector (or scintillation crystal).
