A gamma camera consists of one or more flat crystal planes or, detectors, optically coupled to an array of photomultiplier tubes, the assembly is known as a "head", mounted on a gantry. The gantry is connected to a computer system that both controls the operation of the camera as well as acquisition and storage of acquired images.Figure 9.

Myocardial Perfusion Study with CZT Gamma Cameras Encyclopedia
Myocardial perfusion study has a well-established position in the non-invasive diagnosis of coronary artery disease. According to the guidelines of the European Society of Cardiology (ESC), in patients with an uncertain diagnosis of this disease, myocardial perfusion study is one of the recommended diagnostic methods. Moreover, In this work, we propose and analyze a new concept of gamma ray imaging that corresponds to a gamma camera with a mobile collimator, which can be used in vivo, during surgical interventions for oncological patients for localizing regions of interest such as tumors or ganglia. The benefits are a much higher sensitivity, better image Sensors Free Full-Text Gamma Camera Imaging with Rotating

Gamma correction
Gamma correction is, in the simplest cases, defined by the following power-law expression: where the non-negative real input value is raised to the power and multiplied by the constant A to get the output value . In the common case of A = 1, inputs and outputs are typically in the range 0–1. A gamma value is sometimes called an encoding gammaAbstract: Gamma camera is a powerful tool to locate radioactive sources and contaminations in nuclear facilities. It is widely used in activities decommission, decontamination, maintenance and emergency response of nuclear power plants (NPPs).

Gallbladder radionuclide scan: MedlinePlus Medical Encyclopedia
The health care provider will inject a radioactive chemical called a gamma-emitting tracer into a vein. This material collects mostly in the liver. It will then flow with bile into the gallbladder and then through the common bile duct to the duodenum or small intestine. For the test: You lie face up on a table under a scanner called a gamma camera.Hal Oscar Anger (May 20, 1920 October 31, 2005) was an American electrical engineer and biophysicist at Donner Laboratory, University of California, Berkeley, known for his invention of the gamma camera..
