VMAT SX2

Name (ID): P3Brain, P3Brain (P3Brain)
Plan or PlanSum ID: SX2_6noBrid

This plan was created with .5cm effective MLC leaf width utilizing a works-in-progress software configuration.  Also of note, this plan doesn't include imaging dose in the final calculation.  Otherwise, this plan used simple optimization objectives: max dose constraints to OARs and miniumum dose contraints to targets.  The manual NTO was employed with Priority 140, Distance .3cm, Start Dose 100%, End Dose 8%, Fall Off .25.  Extended convergence mode was selected in the Photon Optimizater calculation options in Eclipse V15.5+.

Multiple distinct targets on the same plane can be a challenge when utilizing coplanar deliver methods.  For this case a special otpimization structure was created to prevent "dose bridging" at the 50% isodoe level.
