The disclosure relates to a method including receiving a first set of images, the images being scans from one or more medical instruments; creating a patient-specific image reconstructed model based on the first set of images; defining mapping points on the reconstructed model; receiving a second set of images; defining patient recognition mapping points on the second set of images; overlaying the reconstructed model and the second set of images based on the mapping points and the recognition mapping points; and displaying the overlaid model aligned with the second set of images.

A surgical navigation system includes a source of a patient anatomy data, wherein the patient anatomy data comprises a three-dimensional reconstruction of a segmented model comprising at least two sections representing parts of the anatomy. A surgical navigation image generator is configured to generate a surgical navigation image comprising the patient anatomy. A 3D display system is configured to show the surgical navigation image wherein the display of the patient anatomy is selectively configurable such that at least one section of the anatomy is displayed and at least one other section of the anatomy is not displayed.

Image guided surgery includes capturing a primary modality image of a surgical field of a patient with a camera system, obtaining a secondary modality image of the surgical field registered to the primary image, generating a surgical guidance image based at least in part upon the secondary modality image, and projecting the surgical guidance image onto the patient. The surgical guidance image presents visual augmentations on or over the patient to inform a medical practitioner during a surgical procedure.

A system for determining a location for a surgical procedure, having a 3D spatial mapping camera, the 3D spatial mapping camera configured to map a bone. The system also includes a marker attached to a distal end section of the bone, such that the 3D spatial mapping camera is configured to capture a plurality of images of the marker as the bone is rotated in a non-linear path. The images also include data identifying a location of the marker. The system also includes a computer system that receives the data from the images captured by the 3D spatial mapping camera and determines a location of a mechanical axis of the bone, and a mixed reality display, where the computer system is configured to send the location of the mechanical axis to the mixed reality display and the mixed reality display is configured to provide a virtual display of the mechanical axis of the bone.

An optical tracking system is provided. The optical tracking system comprises an autoclavable fiducial marker assembly including an opaque housing, a light source, a window panel configured to refract light rays from the light source therethrough, and a metallized coating forming a hermetic seal at an interface of the window panel and the opaque housing. The fiducial marker assembly is configured to shield a peripheral edge of the window panel from the light rays. The system further comprises a tracking device comprising at least two optical sensors configured to detect a position of a light ray emitted by the light source. The system further comprises a processor configured to receive the position of the light rays from the optical sensors, shift the position of each light ray based on a calculated refraction deviation, and triangulate the location of the light source based on the shifted position of each light ray.

A computer-implemented method includes: receiving, by an augmented reality device, a medical image of a surgical site, generating, by the augmented reality device, a virtual surgical site model based on the medical image; presenting, by the augmented reality device, the virtual surgical site model; receiving, by the augmented reality device, user calibration input; aligning, by the ugmented reality device, the virtual surgical site model with a real-life surgical site based on the user calibration input; and displaying, by the augmented reality device and after the aligning, a virtual insertion path between an incision point and a target point to aid in inserting a tool as part of performing a surgical procedure.

Systems, devices and methods are provided for facilitating surgical guidance using a surface detection device. In some example embodiments, a trackable surface detection device is disclosed that includes, in a spatially-fixed relationship, a surface detection subsystem, one or more reference markers that are detectable by a tracking system, and an integrated reference feature that is detectable by the surface detection subsystem for calibration thereof. The trackable surface detection device, which may be handheld, facilitates the determination of a calibration transform that relates a frame of reference of the surface detection subsystem to a frame of reference of the tracking system, which in turn may be employed, in combination with a transform obtained by performing surface-to-surface registration of intraoperatively detected surface data and pre-operative image data pertaining to a subject, when generating an intraoperative display, in a common frame of reference, of the pre-operative image data and a tracked surgical tool.
