Abstract

A method comprising segmenting at least one vertebral body from at least one image of a first three-dimensional image data set. The method comprises receiving at least one image of a second three-dimensional image data set. The method comprises registering the segmented at least one vertebral body from the at least one image of the first three-dimensional image data set with the at least one image of the second three-dimensional image data set. The method comprises determining a position of the at least one surgical implant based on the at least one image of the second three-dimensional image data set and a three-dimensional geometric model of the at least one surgical implant. The method comprises overlaying a virtual representation of the at least one surgical implant on the registered and segmented at least one vertebral body from the at least one image of the first three-dimensional image data set.

First claim

What is claimed is:

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.

2. The system of claim 1 , wherein the first three-dimensional image and the second three-dimensional image include computerized tomography scan images.

3. The system of claim 2 , wherein the initial scan of the surgical site is associated with a higher radiation level than the second scan of the surgical site.

4. The system of claim 1 , wherein the second scan includes a plurality of surgical implants associated with the at least one vertebral body from at least the one image of the first three-dimensional image.

5. The system of claim 1 , wherein segmenting the at least one vertebral body from the first three-dimensional image is determined according to a deep neural network.

6. The system of claim 1 , wherein registering the segmented at least one vertebral body from the first three-dimensional image with the second three-dimensional image includes one or more of a horizontal translation, a vertical translation, a rotation, and a scaling of image information contained within the at least one vertebral body from the first three-dimensional image.
