Advanced Physics for Brachytherapy 2018

1. MBDCAs were NOT developed for single source dosimetry.

2. Such tests are there to introduce you to MBDCA mechanics and serve as a sanity check (correct source, changes with TPS version change, etc).

3. You can review test case results as: local D diff. (to highlight diffs) global D dif. (to factor in their relative importance) plan metrics such as DVH and associated indices (to review their clinical significance)

4. MBDCAs do improve dosimetric accuracy relative to TG-43

5. Potential clinical benefit is treatment site- and patient- specific.
