Technical Plan Comments

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+.
