Quality Assurance Principles for Radiation Therapy

Explains QA principles specific to radiation therapy including machine QA, patient?specific QA, end?to?end testing, and the role of medical physics in ensuring dosimetric accuracy and treatment reproducibility.

Routine QA Tests and Frequency

Detailed descriptions of daily, weekly, monthly and annual QA tasks: output constancy, MLC and imaging QA, end?to?end phantom tests, patient?specific IMRT/VMAT QA, and recommended logging practices and action thresholds.

QA Documentation and Incident Response

How to log QA results, set action thresholds, escalate out?of?tolerance findings to medical physics or service engineers, and document corrective actions and patient safety incident responses for accreditation.
