Explain how an image can be taken using a gamma camera. Describe the entire process, from when a patient is given a radiopharmaceutical to when the image is created.
Explain in detail the path of the gamma radiation through each component in the camera, and the purpose of each part. ( You can use a diagram if needed)

➡Gamma Camera and SPECT. Gamma 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.The special camera and imaging techniques used in nuclear medicine include the gamma camera and single-photon emission-computed tomography (SPECT). The gamma camera, also called a scintillation camera, detects radioactive energy that is emitted from the patient's body and converts it into an image.
