Openpath associates with RadCollision. A tool designed to aid treatment planners in the choice of beam incidence angles.
RadCollision loads a 3D model of a LINAC and or couch into RayStation, that can be rotated interactively to assess collision risk. It makes possible to load in RayStation a 3D scan of the patient done e.g. with a smartphone, if full patient geometry is needed. The interface layer is written in the native IronPython scripting language of the RayStation interface. Check out the RadCollision github here
