Medical Physicist's Notes · Fixed Laser Positioning

Notes for the physicist runningpatient-positioning laser QA.

Each card opens a focused post on one aspect of running the laser-positioning QA — the daily / monthly / annual cadence per AAPM TG-142, drift-response protocol, and how the Saxsons commissioning record feeds the linac-facility QA dossier reviewed at the annual AERB facility inspection. (The laser device itself is a passive Class II red-laser accessory — CDSCO-imported, not AERB-licensed.)
