A gamma camera, also known as a scintillation camera, detects gamma radiation emitted from radioactive tracers administered to a patient during nuclear medicine procedures. When gamma rays interact with the camera's scintillation crystals, they produce flashes of light, which are then converted into electrical signals by photomultiplier tubes. These signals are processed to create images that represent the distribution of the radioactive tracer in the body, allowing for the assessment of various physiological functions and the diagnosis of conditions. The resulting images can provide valuable information about organ function and blood flow.

What is a gamma camera for radiology?

Gamma camera is the common equipment used in nuclear medicine to detect various diseases.Technique used is scintigraphy(detecting amount of radiation emitted) of gamma emission and the intensity is used as images.These images are interpreted by radiologist or nuclear medicine specialists.Common indication for such a study is cancer detection especially bone metastasis.SPECT is a modification.PET(Positron emission Tomography) machine can be made incorporating gamma camera.

How does a gamma scan work?

A gamma scan works by using a gamma camera to detect and capture the gamma radiation emitted by a radioactive substance inside the body. The camera creates images based on the distribution of the radiation, helping to identify any abnormalities or areas of interest, such as tumors or infections. The scan is non-invasive and provides detailed information about the structure and function of organs or tissues.
