## Abstract

Systems, methods, and devices for generating a hybrid image are provided. A preoperative image may be received. A first intraoperative image may be received from an imaging device. The preoperative image and the first intraoperative image may be input into a hybrid model that combines the first intraoperative image with the preoperative image. A hybrid image comprising the preoperative image combined with the first intraoperative image may be generated with an output of the hybrid model.

input the preoperative image and the second intraoperative image into the hybrid model; and
generate, with an output of the hybrid model, an updated hybrid image comprising the preoperative image and the second intraoperative image, wherein the second intraoperative image replaces the first intraoperative image.

### Claim 4 (depends on 3)

The system of claim 3, wherein the preoperative image, the first intraoperative image, and the second intraoperative image each depict at least one anatomical element, wherein the memory stores further data for processing by the processor that, when processed, causes the processor to:
detect movement in the at least one anatomical element based on a difference in the first intraoperative image and the second intraoperative image; and
replace the first intraoperative image with the second intraoperative image when movement is detected.

### Claim 5 (depends on 1)

The system of claim 1, wherein the memory stores further data for processing by the processor that, when processed, causes the processor to:
generate a preoperative three-dimensional representation of one or more anatomical elements using the preoperative image;
and
combine the preoperative three-dimensional representation with the three-dimensional representation.

### Claim 6 (depends on 1)

The system of claim 1, further comprising a navigation system configured to use the hybrid image for navigation of at least one surgical instrument, wherein the memory stores further data for processing by the processor that, when processed, causes the processor to:
generate instructions for navigating the at least one surgical instrument based on the hybrid image.

### Claim 7 (depends on 1)

The system of claim 1, wherein the hybrid image is generated by at least one of merging the first intraoperative image with the preoperative image or the first intraoperative image is overlaid onto the preoperative image.

### Claim 8 (depends on 1)

The system of claim 1, wherein the hybrid model is trained using historical preoperative images and historical intraoperative images.

### Claim 9 (depends on 1)

The system of claim 1, wherein the preoperative image comprises hard tissue information and the first intraoperative image comprises soft tissue information, wherein a first set of pixels represents the hard tissue information and a second set of pixels represents the soft tissue information.

### Claim 10
