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. The applications of scintigraphy include early drug development and nuclear medical imaging to view and analyse images of the human body or the distribution of ...
Hal Oscar Anger (May 20, 1920 – October 31, 2005) [3] was an American electrical engineer and biophysicist at Donner Laboratory, University of California, Berkeley, known for his invention of the gamma camera.
Scintigraphy (from Latin scintilla, "spark"), also known as a gamma scan, is a diagnostic test in nuclear medicine, where radioisotopes attached to drugs that travel to a specific organ or tissue (radiopharmaceuticals) are taken internally and the emitted gamma radiation is captured by gamma cameras, which are external detectors that form two-dimensional images [1] in a process similar to the ...
The 1990s were the dominant decade for ADAC in terms of gamma camera production, manufacturing the Argus, Genesys, Polaris, Thyrus, Transcam, Vertex, Forte and Skylight gamma cameras as well as the EPIC detector and molecular coincidence detection (MCD) option, along with the Pegasys nuclear medicine processing workstation and radiation ...
Later systems used a Sodium iodide (NaI) scintillator, as in a gamma camera. [7] The detector must be connected by mechanical or electronic means to an output system. This could be a simple light source over photographic film, dot matrix printer, oscilloscope or television screen. [8] [9] [10]
In the same way that a plain X-ray is a 2-dimensional (2-D) view of a 3-dimensional structure, the image obtained by a gamma camera is a 2-D view of 3-D distribution of a radionuclide. SPECT imaging is performed by using a gamma camera to acquire multiple 2-D images (also called projections), from multiple angles.
Coded aperture mask for gamma camera (for SPECT) Coded apertures or coded-aperture masks are grids, gratings, or other patterns of materials opaque to various wavelengths of electromagnetic radiation. The wavelengths are usually high-energy radiation such as X-rays and gamma rays. A coded "shadow" is cast upon a plane by blocking radiation in a ...
The term camera is also used, for devices producing images or image sequences from measurements of the physical world, or when the image formation cannot be described as photographic: Acoustic camera which makes sound visible in three dimensions
