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.
It is worn by the person being monitored and is used to estimate the external radiation dose deposited in the individual wearing the device. They are used for gamma, X-ray, beta and other strongly penetrating radiation, but not for weakly penetrating radiation such as alpha particles.
6 gru 2023 · Gamma sterilization is crucial for medical devices, with over 40% of global single-use medical devices sterilized using gamma radiation. It ensures patient safety by eliminating harmful microorganisms, preventing infections, and maintaining medical equipment integrity.
For efficient beta detection in a mixed beta gamma field, Monte Carlo simulation models have been built to optimize the thickness of a plastic scintillator, used in whole body monitor.
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.
8 maj 2021 · Plastic scintillation detectors based whole body β / γ contamination monitors are developed for use in radiation facilities.
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.
