Medical Physicist's Notes · Ge-68 Line Source

Notes for the physicist running PET scanner normalization.

Each card opens a focused post on one aspect of running PET normalization with a Ge-68 line source — NEMA NU-2 cadence, drift detection between scheduled normalizations, and what to re-run after detector or software service.
