Abstract

Described herein are methods and systems for selecting surgical approaches. One example method involves (1) receiving data indicating (a) one or more surgical target regions and (b) one or more surgical portals; (2) determining a plurality of surgical pathways; (3) determining a plurality of surgical approaches; (4) for each surgical approach in the plurality of surgical approaches, determining at least one approach characteristic, for each determined surgical pathway in the respective surgical approach, determining at least one pathway characteristic, and determining a surgical-approach ranking based on the determined at least one approach characteristic and the determined at least one pathway characteristic; (5) selecting a subset of the plurality of surgical approaches based on the determined surgical approach rankings; and (6) causing an output device to provide a representation of the selected subset of the plurality of surgical approaches.
