The Gamma Camera Basic Principles Radiology Key From radiologykey.com
A computer helps create the images from the data obtained by the gamma camera. It detects and amplifies the electrons that are produced by the photocathode. Nuclear Medicine imaging allows us to take pictures of an organ or disease using radio tracers that are selected based on their ability to localise in specific organs. With a digital camera when twice the number of photons hit the sensor it receives twice the signal a linear relationship. The crystal gives a tiny flash of visible light every time a gamma photon hits it. A crystal inside the head of a gamma camera scintillates in response to radioactive particles producing a burst of light that is picked up by sensors located behind the crystal.
The gamma camera can be used for static imaging studies in which an image of an unchanging radionuclide distribution can be recorded over an extended imaging time eg minutes.
Low-energy gamma-ray imaging is very awkward and primitive in many respects. Simplified introduction to how the gamma camera works for first year students - without getting into the physics and electronics too deeply. The gamma camera is made to scan the area of interest approximately four hours after the patient has been injected with the radioactive tracer. What preparation is needed. The photocathode when stimulated by. Gamma Camera contains 37 -91 PMT.

Nuclear Medicine Gamma camera imaging. The gamma camera is used to generate images from the ionizing radiation that is emitted from the body. The gamma camera also called a scintillation camera detects radioactive energy that is emitted from the patients body and converts it into an image. Single contiguous images of the whole body can be obtained by scanning the gamma camera across the entire length of the patient. The radioactivity is converted to electrical impulses by the camera and the information is passed to a computer which produces an image on a TV screen.

Simplified introduction to how the gamma camera works for first year students - without getting into the physics and electronics too deeply. A crystal inside the head of a gamma camera scintillates in response to radioactive particles producing a burst of light that is picked up by sensors located behind the crystal. The technology not only offers better sensitivity and high energy resolution but it also makes the camera smaller in size than a traditional MRI machine. Scintigraphy scans get their name from the ability of some crystals such as sodium iodide to scintillate in other words emit. Sometimes the gamma camera heads are oriented at a 90 degree angle and placed over the patients body.

Simplified introduction to how the gamma camera works for first year students - without getting into the physics and electronics too deeply. The crystal gives a tiny flash of visible light every time a gamma photon hits it. Only gamma propagating along the channel axis reach the scintillator where they deposit their energy generating a brief flash of light. The camera typically comprises of a flat and narrow table on which the patient must lie down. This flash is picked up by photomultipliers which convert the flash into into an electrical signal.
