Dosimetric analysis of different whole brain radiotherapy treatment planning methods: three types of 3-dimensional versus hippocampal avoidant

We showed adequate and equivalent target coverage using OL, OLS, and optDCA techniques. Lacrimal and parotid dosages can be greatly reduced with the implementation of minor MLC adjustments. OptDCA therapy represented further improvement of these modifications, and was comparable to HA-WBRT in terms of OAR dose, while being about two-thirds the cost and more efficient to plan.
