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 camera imaging enables quantitative analysis, providing measurable data on the distribution and concentration of radiopharmaceuticals within the body. This quantitative aspect enhances the accuracy of diagnoses and aids in treatment planning and monitoring.
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.
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).
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.
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.
13 gru 2019 · The gamma camera involves the use of a radiation sensitive crystal that detects the distribution of the tracer within the patient’s body. The information is converted to a digital format to produce a two- or three-dimensional image on a monitor screen.
