A gamma camera (γ-camera), also called a scintillation camera or Anger camera, is a device used to image gamma radiation emitting radioisotopes, a technique known as scintigraphy.
Gamma cameras detect high-energy “gamma” photons from the radioactive atoms in the patient’s body. These photons escape the patient’s body and enter the gamma camera after passing through a collimator, which is a set of metal tubes organized in the style of a matrix.
26 lut 2016 · In this chapter, we discuss briefly some general aspects of radionuclide imaging, and we describe the basic principles of the most widely used imaging device, the gamma camera, also known as the Anger scintillation camera, named after its inventor, Hal Anger (see Chapter 1, Section C and Fig. 1-3).
16 maj 2021 · Nuclear medicine instruments designed to image x- and γ -ray-emitting radionuclides (gamma cameras) use collimators that permit photons following certain trajectories to reach the detector but absorb most of the rest. A heavy price is paid for using collimation—the vast majority (typically well over 99.95%) of emitted photons is wasted.
The gamma camera or SPECT camera is a camera that is able to detect scintillations (flashes of light) produced when gamma rays, resulting from radioactive decay of single photon emitting radioisotopes, interact with a sodium iodide crystal at the front of the camera.
14 lis 2023 · A vital tool in nuclear medicine is the gamma camera, sometimes referred to as the scintillation camera (see Image. Gamma Camera). In addition, other critical instruments used in nuclear medicine include positron emission tomography (PET) cameras, single-photon emission computed tomography (SPECT) systems, and various detectors and counters.
27 maj 2021 · The basic components of gamma camera are collimator, scintillation crystal, photomultiplier tubes, and electronic circuitry including preamplifiers, amplifiers, and multichannel analyzers along with analog to digital converters. Those components were briefly reviewed in this chapter.
