Medical Physicist's Notes · Co-57 Flood Source

Notes for the physicist running thegamma-camera uniformity QA programme.

Each post here covers one aspect of running daily uniformity QA with a Co-57 flood source — the operator-side checklist, NEMA NU-1-2007 quantitative metrics, AAPM TG-22 / TG-150 cadence, and what to do when a uniformity test fails.
