1. A method of pre-operative surgical planning, comprising:
generating a pre-resection 3D model of a tissue structure;
displaying the pre-resection 3D model of the tissue structure on a user interface;
determining tissue function information for the pre-resection 3D model of the tissue structure;
simulating, on the pre-resection 3D model, collapsing the tissue structure to generate a collapsed pre-resection 3D model;
displaying the collapsed pre-resection 3D model;
selecting a portion of tissue to remove from the collapsed pre-resection 3D model;
simulating, on the collapsed pre-resection 3D model, removal of the selected portion of tissue to produce a post-resection 3D model including a change in overall shape of the tissue structure from the pre-resection 3D model due to removal of the selected portion of tissue;
simulating, on the post-resection 3D model, inflation of the tissue structure to generate an inflated post-resection 3D model;
displaying the inflated post-resection 3D model; and
determining tissue function information for the inflated post-resection 3D model of the tissue structure.
