Scintillation or gamma camera

A camera, somewhat like an x-ray machine, used to photograph internal organs after the patient has been injected with a radioactive material.

1. the emission of sparks.
2. a particle emitted in disintegration of a radioactive element.

scintillation camera
a stationary device that records a photographic image of the distribution of radioactivity of an organ after the administration of a radionuclide. A sequence of photographs records the uptake and the distribution of the radionuclide.
