1 3D Dosimetry in the Clinic and Research 3D DOSIMETRY IN END-TO-END DOSIMETRY QA Geoffrey S. Ibbott, PhD Department of Radiation Physics MD Anderson Cancer Center
2 Disclosures My institution holds Master Research Agreements with Varian, Elekta, and Philips I will be discussing devices that are not currently available for sale, and that do not have FDA clearance.
3 Learning objectives 1: 3D Dosimetry in the Clinic: Background and Motivation 2: 3D Dosimetry in the Clinic: Motion interplay effects in dynamic radiotherapy 3: 3D Dosimetry in the Clinic and Research: Validating Special Techniques 4: 3D Dosimetry in end-to-end dosimetry QA Evidence of need for E2E dosimetry Benefits of 3D dosimetry for E2E testing Specific examples of 3D dosimetry and E2E tests
4 Errors in Radiation Therapy 1. Errors in medicine occur too often IOM study: ~98,000 deaths/year New York Times series: St. Vincent s Hospital: IMRT error Moffitt Cancer Center: Calibration error 2. QA is essential Equipment is more complex Techniques are more complex Risk to patient from error is greater Most institutions report insufficient staff
5 What causes things to go wrong?* Selected Causes/Contributing factors Therapist error 84% Failure to follow policies/procedures 63% Incorrect body part 46% Physics/Dosimetry 27% Wrong patient 19% Inadequate policies/procedures 16% RO error 12% *New York State Courtesy Peter Dunscombe: Safety in Radiation Therapy: A call to action
