Abstract: A surgical tool tracking array can include a first marker holder, a second marker holder, and a tool holder. The first marker holder is configured to couple a first marker to the surgical tracking array in a first plane. The second marker holder is configured to couple a second marker to the surgical tool tracking array in a second plane that is independent and substantially parallel to the first plane. The tool holder is configured to couple a portion of a surgical tool to the surgical tool tracking array in a third plane that is independent from the first plane and the second plane.

Abstract: A camera tracking system for computer assisted navigation during surgery operatively determines a first pose of a second extended-reality (XR) headset relative to stereo tracking cameras located on a first XR headset based on first tracking information from the stereo tracking cameras. The camera tracking system determines a second pose of eyes of a user wearing the second XR headset relative to the stereo tracking cameras located on the first XR headset based on second tracking information from the stereo tracking cameras. The camera tracking system also calibrates an eye-to-display relationship defining pose of the eyes of the user wearing the second XR headset to a display device of the second XR headset based on the determined first and second poses. The camera tracking system also controls where symbols are displayed on the display device of the second XR headset based on the eye-to-display relationship.

Abstract: A camera tracking bar of a camera tracking system for computer assisted surgery navigation. The camera tracking bar includes a first set of stereo tracking cameras having first resolution, first field of view, and spaced apart on the camera tracking bar by a first baseline distance. The camera tracking bar also includes a second set of stereo tracking cameras having second resolution, second field of view, and spaced apart on the camera tracking bar by a second baseline distance that is less than the first baseline distance. The second set of stereo tracking cameras is positioned between the first set of stereo tracking cameras, and the resolution and/or the field of view of the second set of stereo tracking cameras is different from the resolution and/or the field of view of the first set of stereo tracking cameras. A communication interface provides camera video streams to the camera tracking subsystem.

Abstract: An augmented reality surgical system includes a head mounted display (HMD) with a see-through display screen, a motion sensor, a camera, and computer equipment. The motion sensor outputs a head motion signal indicating measured movement of the HMD. The computer equipment computes the relative location and orientation of reference markers connected to the HMD and to the patient based on processing a video signal from the camera. The computer equipment generates a three dimensional anatomical model using patient data created by medical imaging equipment, and rotates and scales at least a portion of the three dimensional anatomical model based on the relative location and orientation of the reference markers, and further rotate at least a portion of the three dimensional anatomical model based on the head motion signal to track measured movement of the HMD. The rotated and scaled three dimensional anatomical model is displayed on the display screen.

Abstract: A virtual model a planned instrument attachment can be provided to ensure correct selection of a physical instrument attachment. An XR headset controller can generate a shape and a pose of the virtual model of the planned instrument attachment based on predetermined information associated with the planned instrument attachment and based on a pose of an instrument relative to the XR headset. An XR headset can display the virtual model on a see-through display screen of the XR headset that is configured to allow at least a portion of a real-world scene to pass therethrough.

Abstract: A camera tracking system for computer assisted navigation during surgery. The camera tracking system includes a processor operative to receive streams of video frames from tracking cameras which image a plurality of physical objects arranged as a reference array. For each of the physical objects imaged in a sequence of the video frames, that processor determines a set of coordinates for the physical object over the sequence of the video frames. For each of the physical objects, the processor generates an arithmetic combination of the set of coordinates for the physical object. The processor generates an array template identifying coordinates of the physical objects based on the arithmetic combinations of the sets of coordinates for the physical objects, and tracks pose of the physical objects of the reference array over time based on comparison of the array template to the reference array imaged in the streams of video frames.
