Abstract: A virtual beam's-eye view of a planning target volume is generated based on volumetric image data acquired immediately prior to radiation therapy by a radiation therapy system. The virtual beam's-eye view can then be displayed to confirm that, with the patient disposed in the current position, the planned beam-delivered treatment extends beyond the surface of the skin. In some embodiments, the virtual beam's-eye view can be displayed in conjunction with a beam's-eye view that is generated based on volumetric image data acquired during treatment planning, to create a blended beam's-eye view. In some embodiments, a field outline of a treatment beam can be superimposed on the blended beam's-eye view, thereby illustrating whether the planned beam-delivered treatment extends beyond the surface of the skin of the patient. The blended beam's-eye view can facilitate a manual confirmation process that verifies the planned beam-delivered treatment extends beyond the surface of the skin.

Abstract: Respective target positions, into which elements of a radiation therapy machine are to be moved (e.g., prior to beginning treatment of a patient), are determined. A candidate path, which describes movements of the elements from respective initial positions to the respective target positions, is defined and accessed. The candidate path is evaluated to determine whether it would result in a collision between any of the elements. The candidate path is included in a set of candidate paths when the candidate path does not result in a collision between any of the elements. A value of a measure (e.g., a measure of efficiency), used for ranking each candidate path in the set of candidate paths, is determined. A path is selected from the set of candidate paths based on the ranking.
