SGRT Forum

We are currently evaluating open masks for SGRT pathway on the Halcyon. The Halcyon is a 6FFF beam, and we are finding that the buildup effect is higher for the open mask that we were considering. Has anyone done an assessment of open masks for 6FFF?

we are trialling different masks, but haven't started using them yet. we would use with 6x and 10fff. are the masks thicker? could you just contour the mask in TPS and let it deal with it?
