WE‐D‐BRB‐01: Support for Staffing and Assuring Quality in Radiation Oncology
Bibliographic record
Abstract
Standards for commissioning and quality control of radiation therapy equipment have traditionally been established through the consensus of “experts”. The recently implemented Canadian approach to standards (medphys.ca) has broadened the expert panel to include the entire Canadian medical physics community through web‐based consultation. This process and the standards so developed will be discussed. A limitation is that while such standards developed to date in Canada and in many other jurisdictions undoubtedly have made major contributions to the safety and quality of radiation therapy, they could not be described as being evidence based. An approach to “evidence based” commissioning of a treatment planning system, in which the Equivalent Uniform Doses of targets and organs at risk are used as outcome surrogates, will be discussed. The resulting Quality Control Standards, whether using the novel Canadian approach or the more traditional AAPM Task Group approach, require a determinable amount of time that must be performed by medical physicists. Staffing at appropriate levels to accomplish these tasks is the focus of all activities in medical physics. Proper staffing is therefore crucial to patient care, and necessary to meet regulatory requirements. The results from the Abt study of medical physicist work values for radiation oncology physics services: round III may be used to justify personnel and defend staffing to administration for a number of venues of practice. A work model is created to allow the medical physicist to defend QMP work based on both routine and special procedures service mix. The model may be used to develop a cost‐justification report for setting charges for radiation oncology physics services. Objectives: 1. Understand alternative options to develop Quality Control Standards for Radiation Oncology Physics. 2. Understand what new information will be provided in the Abt III study. 3. Understand how to use the Abt studies to justify medical physicist work and staffing.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
