Routine linac quality assurance is now largely automated and log-file based, so one physicist could review it remotely while trained radiation therapists take the measurements, covering three to five machines once regulators define the supervision standard.","summary":"Routine linac quality assurance (output constancy, imaging alignment, plan verification) is increasingly automated and log-file based. A physicist can review these remotely while trained radiation therapists perform the physical measurements. Coupled with remote plan checks and periodic on-site audits, this model could let one physicist supervise three to five machines across sites. Regulators and professional bodies would need to define the supervision standard.","asOf":"2026-09-08","links":[{"label":"Bottleneck evidence (Not enough oncologists, nurses, pathologists, physicists): Yang et al., Projected supply of and demand for oncologists and radiation oncologists through 2025 (JOP 2014)","url":"https://doi.org/10.1200/JOP.2013.001319"}],"tags":[],"related":["idea-acc-remote-planning-hubs"],"cancers":[],"sections":["radiation"],"technologies":["imrt-igrt"],"targets":[],"drugs":[],"companies":[],"institutions":[],"pathways":[],"terms":[],"trials":[],"people":[],"bottlenecks":["b-workforce","b-global-access"],"keyPapers":["paper-yang-j-oncol-pract"],"journals":[],"dependsOn":[],"notes":[],"hypothesis":"A remote-supervision model will maintain IAEA/IROC dosimetry audit pass rates equivalent to on-site physics while reducing the physicist requirement per machine by at least half.","rationale":"Automated QA and log-file analysis already meet or exceed manual checks in accuracy; the constraint is professional custom and regulation rather than physics.","test":"Run a two-year pilot in a network of six machines with two physicists, using independent external dosimetry audits and incident reporting as safety endpoints.","maturity":"early-clinical","actor":"engineering","cost":"medium","horizonYears":3},"route":"/ideas/idea-acc-remote-medical-physics-qa/","neighbours":{"idea":[{"id":"idea-acc-remote-planning-hubs","kind":"idea","name":"Round-the-clock remote treatment-planning hubs for clinics without physicists","route":"/ideas/idea-acc-remote-planning-hubs/"}],"section":[{"id":"radiation","kind":"section","name":"Radiation Therapy","route":"/fronts/radiation/"}],"technology":[{"id":"imrt-igrt","kind":"technology","name":"IMRT / IGRT (modern external beam)","route":"/technologies/imrt-igrt/"}],"bottleneck":[{"id":"b-global-access","kind":"bottleneck","name":"Most of the world has almost no cancer care","route":"/bottlenecks/b-global-access/"},{"id":"b-workforce","kind":"bottleneck","name":"Not enough oncologists, nurses, pathologists, physicists","route":"/bottlenecks/b-workforce/"}],"paper":[{"id":"paper-yang-j-oncol-pract","kind":"paper","name":"Projected supply of and demand for oncologists and radiation oncologists through 2025: an aging, better-insured population will result in shortage","route":"/key-papers/paper-yang-j-oncol-pract/"}],"roadmap":[{"id":"radiation-roadmap","kind":"roadmap","name":"Radiotherapy roadmap: X-rays → shaped beams → fewer fractions, particles and FLASH","route":"/roadmaps/radiation-roadmap/"}]}}
