Medical Physicist's Notes · LUCY™ 3D QA Phantom

Notes for the physicist commissioning and running SRS / SRT / SBRT end-to-end QA.

Each card opens a focused post on one aspect of running the LUCY 3D phantom inside an AAPM MPPG 9.a end-to-end QA programme — what the per-component 0.1 mm tolerance contributes to the uncertainty budget, how the published Sarkar 2016 head-to-head reads, and where the MR distortion inserts fit a modern MR-only or MR-guided workflow.
