What a gamma camera does

What a gamma camera does

Cross-sectional diagram of a gamma camera showing a patient with a radioactive tracer, a lead collimator, a NaI(Tl) scintillator, a light guide, a photomultiplier tube array, and a computer building a 2D image

Gamma cameras detect gamma photons emitted by a radioactive tracer inside the patient. The camera is a passive detector, so unlike an X-ray machine it does not send radiation into the body.

Step-by-step lessons on AQA A Level Physics Gamma camera (A-level only). Each one builds up to exam-style questions. Physics is one of the most mathematically demanding A Levels -- at least 40% of the marks require maths skills at Level 2 (GCSE) standard or above, so build calculation and graph-handling fluency alongside the conceptual content from the start.
