Anger camera

Definition

An Anger camera, also known as a gamma camera, is a device used in nuclear medicine to image gamma radiation emitting radioisotopes. It converts gamma rays into light, which is then detected to form an image.

5 Must Know Facts For Your Next Test

1. The Anger camera was invented by Hal O. Anger in 1957.
2. It uses a scintillation crystal to convert gamma rays into visible light.
3. A photomultiplier tube (PMT) array detects the light and converts it into electrical signals.
4. The Anger camera provides functional imaging of organs and tissues by detecting emitted gamma photons from radiopharmaceuticals within the body.
5. It is commonly used in procedures such as SPECT (Single Photon Emission Computed Tomography).
