AAPM task group 324 report 91.b: The management of respiratory motion in radiation oncology

Abstract The Task Group charge was to provide a concise, updated report of American Association of Physicists in Medicine Task Group 76: The Management of Respiratory Motion in Radiation Oncology to describe new technology, new knowledge, and practice changes since the original 2006 publication. The updated report includes a revised literature review, new respiratory motion management technologies that have emerged and are clinically practiced, and revised recommendations of clinical processes and quality assurance. To have broad applicability and to not overlap with existing task group reports, the current report scope focuses on technologies available to most clinics: four‐dimensional computed tomography, treatment planning systems, and linear accelerators with gantry‐mounted X‐ray guidance. The deliverables from the current report include an explanation of respiratory motion management; terms and definitions relevant to respiratory motion management; the clinical benefit of, clinical experience with, and clinical implementation guidelines for respiratory motion management; quality assurance guidelines; a clinical decision pathway; future outlook; and overall recommendations.
