Couch shift accuracy and image-registration performance are central to MR-guided radiotherapy, yet QA is often interpreted with fixed tolerances alone. This study applied statistical process control (SPC) to derive machine-specific 2σ (warning) and 3σ (action...

Daily QA tolerances are often implemented as fixed pass/fail thresholds, yet MR-Linac performance can be facility-specific and may evolve over time. This study used statistical process control (SPC) to establish global, machine-specific 2σ warning and 3σ acti...
