Volumetric modulated arc therapy with dynamic collimator rotation for improved multileaf collimator tracking of the prostate.

CONCLUSION: Prostate VMAT plans with rotating collimator were of similar quality as fixed collimator plans, but more suitable for MLC tracking with significantly better agreement between planned and delivered dose distributions. MLC tracking for prostate cancer patients can therefore be improved without the requirement of additional efforts or hardware changes. PMID: 27908453 [PubMed - as supplied by publisher]
