Report 142 (Quality Assurance of Medical Accelerators) partially supersedes TG40
AAPM Task Group 142 Report: Quality Assurance of Medical Accelerators was recently published (Med. Phys. Volume 36, Issue 9, pp. 4197-4212, September 2009). The Therapy Physics Committee of Science Council has approved this report, and it is recommended that physicists adopt the recommendations of TG-142 as they supersede the recommendations of Table II (linear accelerator QA) of TG-40. This new report makes specific recommendations regarding technologies that were adopted after the release of TG-40 (MLC, newer wedge systems, asymmetric jaws, imaging systems, and respiratory systems) along with specific recommendations for procedures such as SRS, SBRT, TBI and IMRT.
