1. A method of automatically determining a geometry of an implant, comprising:
accessing image data of a subject having identified at least a first portion and a second portion of the subject;
determining a pose of the implant relative to a pose of the first portion of the subject and a pose of the second portion of the subject, wherein the implant includes at least a first portion independently moveable relative to a second implant portion;
determining a geometry of a region of interest between the first portion of the subject and the second portion of the subject with a processor;
determining a geometry of the implant including the first implant portion and the second implant portion in the determined pose of the implant based at least on the determined geometry of the region of interest and wherein the geometry of the implant includes at least a shape that is operable to fit within an external boundary defined and determined by the determined geometry of the region of interest with the processor; and
displaying the determined geometry of the implant for assisting in performing a procedure.
