WE-F-201-02: Review TG-186 and WGMBDCA Guidelines, Commission Process, and Dosimetry Benchmarks

Authors


Abstract

With the recent introduction of heterogeneity correction algorithms for brachytherapy, the AAPM community is still unclear on how to commission and implement these into clinical practice. The recently-published AAPM TG-186 report discusses important issues for clinical implementation of these algorithms. A charge of the AAPM-ESTRO-ABG Working Group on MBDCA in Brachytherapy (WGMBDCA) is the development of a set of well-defined test case plans, available as references in the software commissioning process to be performed by clinical end-users. In this practical medical physics course, specific examples on how to perform the commissioning process are presented, as well as descriptions of the clinical impact from recent literature reporting comparisons of TG-43 and heterogeneity-based dosimetry.

Learning Objectives:

  • 1.Identify key clinical applications needing advanced dose calculation in brachytherapy.
  • 2.Review TG-186 and WGMBDCA guidelines, commission process, and dosimetry benchmarks.
  • 3.Evaluate clinical cases using commercially available systems and compare to TG-43 dosimetry
