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.
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 ...
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.
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. From: Interventional Spine, 2008.
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 ...
This article provides an in-depth exploration of the gamma camera in medical imaging, highlighting its development, functioning, applications, and the advantages and limitations it presents in modern medical practice.
16 maj 2021 · Because charged particles from radioactivity in a patient are almost entirely absorbed within the patient, nuclear imaging uses γ-rays, characteristic x-rays (usually from radionuclides that decay by electron capture), or annihilation photons (from positron-emitting radionuclides) to form images.
