    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： A system for adjusting an operating state of a medical electronic device is described. In an aspect, the system includes an optical tracking system configured to detect three or more tracking markers. The system also includes a processor coupled with the optical tracking system. The processor is programmed with instructions which, when executed, configure the processor to: configure an input command by assigning at least one operating state of the medical electronic device to a particular state of at least one of the tracking markers; after receiving a priming command, identify a present state of the tracking markers based on data from the optical tracking system; compare the present state with the particular state assigned to the operating state; and based on the comparison, determine that an input command has been received and adjust the operating state of the medical electronic device to the assigned operating state.

    摘要： A method for updating a patient registration during a medical procedure is disclosed. The medical procedure uses an optical navigation system for optically tracking a patient reference object in a real-world space. The method includes: acquiring a first set of image data depicting a region of interest on the patient while a first patient registration is intact; detecting that the first patient registration has been lost; obtaining a second set of image data depicting the region of interest; and applying a transform to data points of the first region to obtain data points for an updated patient registration, the transform obtained based on the first and second sets of image data.

    摘要： A medical navigation system is provided for detecting movement of a subject, the system having an optical tracking system including a camera, a display, and a controller electrically coupled with the optical tracking system and the display. The controller has a processor coupled with a memory and is configured to receive a data signal from the optical tracking system and recognize and continuously monitor optical tracking markers on the subject within a field of view of the camera, and provide an alert on the display when movement of the optical tracking markers on the subject falls within predefined parameters.
