1. A system for generating a display of an image of a patient's internal anatomy during a surgical procedure comprising:
a display and a processor in communication with the display, wherein the processor is configured to:
segmenting at least one vertebral body from a first three dimensional image, wherein the first three-dimensional image is based on an initial scan of a surgical site that includes spinal anatomy, to provide a segmented at least one vertebral body;
receiving a second three-dimensional image, wherein the second three-dimensional image is based on a second scan of the surgical site subsequent to the initial scan of the surgical site, wherein the second scan of the surgical site includes the spinal anatomy and at least one surgical implant;
registering the segmented at least one vertebral body from the first three-dimensional image with image data of the second three-dimensional image, to provide a registered and segmented at least one vertebral body from the first three-dimensional image;
determining a position of the at least one surgical implant based on the image data of the second three-dimensional image and a three-dimensional geometric model of the at least one surgical implant, to provide a determined position of the at least one surgical implant; and
based on the determined position of the at least one surgical implant, overlaying a virtual representation of the at least one surgical implant on the registered and segmented at least one vertebral body from the first three-dimensional image.
