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 ...
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 ...
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 EMI 2001 broadcast studio camera was an early, very successful British made Plumbicon studio camera that included the lens within the body of the camera. Four 30 mm tubes allowed one tube to be dedicated solely to producing a relatively high resolution monochrome signal, with the other three tubes each providing red, green and blue signals.
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 .
Human communication was initiated with the origin of speech approximately 100,000 BCE. [1] Symbols were developed about 30,000 years ago. The imperfection of speech allowed easier dissemination of ideas and eventually resulted in the creation of new forms of communication, improving both the range at which people could communicate and the longevity of the information.
Multi-headed gamma cameras can accelerate acquisition. For example, a dual-headed camera can be used with heads spaced 180 degrees apart, allowing two projections to be acquired simultaneously, with each head requiring 180 degrees of rotation. Triple-head cameras with 120-degree spacing are also used.
