Session Title: Report of TG 182: Electronic Intracavitary Brachytherapy Quality Management Based on Risk Analysis
Question 1: Why doesn’t TG 182 present a prescriptive list of QM procedures?
Reference:M. S. Huq, B. A. Fraass, P. B. Dunscombe, J. P. Gibbons, Jr., G. S. Ibbott, A. J. Mundt, et al., The report of Task Group 100 of the AAPM: Application of risk analysis methods to radiation therapy quality management. Med Phys 2016 Vol. 43 Issue 7 Pages 4209 Accession Number: 27370140 PMCID: PMC4985013 DOI: 10.1118/1.4947547 https://www.aapm.org/pubs/reports/detail.asp?docid=156
Choice A:The list just gets too long for any clinic to do.
Choice B:The members of the task group had very strong and divergent opinions on what needs to be done.
Choice C:The QM depends not only on the device but on the procedures as practiced at a facility.
Choice D:A list of QM procedures should come from a Medical Physics Practice Guideline.
Question 2: According to TG 100, QM design Should come from which of the following?
