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.
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.
The gamma camera, also called scintillation camera, is the most commonly used imaging device in nuclear medicine. It simultaneously detects radiation from the entire FOV and enables the acquisition of dynamic as well as static images of the area of interest in the human body [67] .
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 · 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.
20 mar 2020 · One particular meter, known as a teletector, is specifically designed to detect gamma and x-ray radiation. Named for its "telescoping" ability, this device can be extended to about 4 meters (13 feet) to measure very high dose rates without subjecting the user to unnecessary exposure.
