Abstract
A boost or partial breast PTV margin of â¼10Â mm, is possible with zero imaging dose and workload, however, patients receiving boost radiotherapy may benefit from a margin reduction of â¼4Â mm with imaging doses from 0.4Â cGy to 25Â cGy using an eNAL protocol. PTV margin contributions from deformation errors are likely to be small in comparison to other sources of error, i.e., set up or delineation.
