Abstract: Methods and apparatus for enhancing surgical planning provide enhanced planning of entry port placement and/or robot position for laparoscopic, robotic, and other minimally invasive surgery. Various embodiments may be used in robotic surgery systems to identify advantageous entry ports for multiple robotic surgical tools into a patient to access a surgical site. Generally, data such as imaging data is processed and used to create a model of a surgical site, which can then be used to select advantageous entry port sites for two or more surgical tools based on multiple criteria. Advantageous robot positioning may also be determined, based on the entry port locations and other factors. Validation and simulation may then be provided to ensure feasibility of the selected port placements and/or robot positions. Such methods, apparatus, and systems may also be used in non-surgical contexts, such as for robotic port placement in munitions diffusion or hazardous waste handling.
