Table 1 The details of the review items
Categories | Details |
|---|---|
Parameter consistency | Consistency between treatment delivery parameters and treatment plan parameters, which included scrutiny of machine specifications, modality, energy, beam type, source-to-surface distance (SSD), segment count, monitor units (MU), gantry angle, collimator settings, couch angle, jaw configuration, and multi-leaf collimator (MLC) positions, etc |
Treatment completeness | Delivery of all treatment fields in the plan |
Delivered MU did not exceed planned MU | |
Treatment progression | Cumulative dose and remaining dose |
Accuracy of the remaining session | |
Consistency between the daily treatment dose and the prescribed dose | |
Treatment calendar that has been postponed for an extended period or discontinued altogether | |
Dose verification prior to stereotactic treatment | |
Image guidance | Image approval in accordance with departmental policies |
Applied shifts | |
Isocenter on the CBCT(cone-beam computed tomography) matched plan | |
Selection of IGRT (image-guided radiation therapy) scan template and parameters meet clinical requirements | |
IGRT frequency adherence to medical directives | |
IGRT registration deviation did not exceed predefined threshold | |
Overrides | Override records, including instances such as couch position exceeding tolerance, inconsistent field parameters, abnormal dose tracking, treatment fractionation mode not consistent with the prescription, and any other deviations |
Treatment couch | Discrepancies between the treatment couch position (vertical, lateral, longitudinal, and rotational) and the reference couch position |
Documentation | Completeness of treatment-related documentation |
Approval of documents by both the planning physicist and review physicist | |
Treatment mode | Treatments completed out of clinical mode |
The individual performing the QA model treatment |
