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...

To assess the feasibility of prostate stereotactic body radiation therapy (SBRT) in patients with unilateral and bilateral hip prostheses across multiple treatment platforms, focusing on image quality, planning feasibility, delivery characteristics, motion ma...
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...
To compare head-and-neck (HN) IMPT robustness using a conventional systematic setup uncertainty model versus a probabilistic random (interfractional) setup uncertainty model.
