摘要: A method and device for tracking objects by surgical navigation systems. The method includes: capturing an image of the tracked object; determining whether a unique identifiable feature associated with at least one totem pattern is discernible in the image; when the unique identifiable feature is discernible: determining a position or an orientation of the tracked object based on the at least one totem pattern; and registering the at least one totem pattern in the surgical coordinate space; and when the unique identifiable feature is indiscernible: determining a position of each totem pattern relative to other totem patterns such that a combination of totem patterns within the captured image is a marker group detectable as a composite totem pattern; determining a position or an orientation of the tracked object based on the composite totem pattern associated with the tracked object; and registering the composite totem pattern in the surgical coordinate space.

摘要: An optical imaging system for imaging a target during a medical procedure, the imaging system involving an optical assembly having moveable zoom optics and moveable focus optics, a zoom actuator and a focus actuator for positioning the zoom and focus optics, respectively, a controller for controlling the zoom and focus actuators independently in response to received control input, a camera for capturing an image of the target from the optical assembly, the system capable of performing autofocus during a medical procedure.

摘要: 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.
