Abstract

Methods, systems, and programs for real-time surgical procedure assistance are provided. A first set of 3D poses of the 3D points on the organ may be received. An electronic organ map built for the organ via pre-surgical medical information may be retrieved. A tissue parameter of the organ may be obtained based on the first set of 3D poses and their corresponding 3D poses from the electronic organ map. A deformation transformation of the electronic organ map may be calculated based on the obtained tissue parameter and the first set of 3D poses during the surgical procedure. The deformed electronic organ map may be projected onto the organ with respect to the first set of 3D poses during the surgical procedure.
