Methods and systems for providing feedback during a medical procedure. The 3D position and orientation of a tracked tool are determined, relative to a site of the medical procedure, based on tracking information received from a tracking system. The 3D position and orientation are mapped to a common coordinate space, to determine the 3D position and orientation relative to a field-of-view (FOV) of an optical camera that is capturing an optical image of the site. Navigational information associated with the 3D position and orientation is determined. A virtual representation of the navigational information overlaid on the FOV and displayed. The displayed virtual representation is updated when the 3D position and orientation of the tracked tool changes or when the FOV changes, in accordance with the change.

Methods and systems for providing visuospatial information

Methods and devices to track patient anatomy during a surgical operation. A patient reference device is attached to an anatomical feature of a patient and it includes an attachment base and an optically-trackable array detectable by an optical navigation system and having a longitudinally-extending arm to space apart the fixed geometric pattern from the anatomical feature. The arm includes a connector to be detachably secured to the attachment base. An inertial measurement unit within the attachment base enables determining, based on comparing a threshold level to a motion signal, that the attachment base has changed position, wherein the motion signal represents the change in position and its magnitude. Based on determining that the attachment base has changed position an alarm signal is generated an and an output device in the attachment base outputs an alarm in response to the alarm signal.

Methods and systems of performing intraoperative image registration during a medical procedure are described. A depth-encoded marker is provided to an object of interest. The marker is imageable by at least two imaging systems. The marker has asymmetry in at least a depth dimension. First and second sets of image data are obtained. Tracking data is obtained. The first image coordinate space, the second image coordinate space and the tracking coordinate space are independent from each other. Transformation mapping is performed to register the first and second sets of image data and the tracking data to each other. The first and second sets of image data are mapped to each other based on the depth-encoded marker. The first or second set of image data and the tracking data are mapped to each other based the same or different marker.
