1. A system for mesh registration, the system comprising: a processor and a processor storage medium having instructions stored thereon, the processor configured by the instructions stored on the processor storage medium to: extract a preoperative anatomical mesh from a preoperative anatomical image based on a base topology of an anatomical mesh template; extract an intraoperative anatomical mesh from an intraoperative anatomical image based on a preoperative topology of the preoperative anatomical mesh derived from the base topology of the anatomical mesh template; and register the preoperative anatomical image and the intraoperative anatomical image based on a mapping correspondence between the preoperative anatomical mesh and the intraoperative anatomical mesh established by an intraoperative topology of the intraoperative anatomical mesh derived from the preoperative topology of the preoperative anatomical mesh.
