Assignee: MAZOR ROBOTICS LTD.
Field: Medical technology (Instruments)
Classification: CPC A  G | IPC A  G

Claim 7:
8. A method to form a single virtual tracking device with a trackable member, comprising:
removably fixing a robotic system in a volume;
moving the trackable member with a moveable portion of the robotic system to a first position;
moving the trackable member with the moveable portion of the robotic system to a second position;
performing a navigation tracking system tracking by (i) tracking the first position of the trackable member with a navigation tracking system in a navigation coordinate system and (ii) tracking the second position of the trackable member with the navigation tracking system in the navigation coordinate system;
performing a robotic system tracking separate from the navigational tracking system by (i) tracking the first position with a robotic tracking system in a robotic coordinate system separate from the navigation tracking system and (ii) tracking the second position with the robotic tracking system separate from the navigation tracking system in the robotic coordinate system;
defining the single virtual tracking device with the trackable member by moving the trackable member between the first position and a second position; and
correlating the navigation tracking system and the robotic tracking system with the defined single virtual tracking device;
wherein the defined single virtual tracking device is defined by both the first and second positions of the trackable member used in concert and coordinated to define a single virtual array larger than the trackable member to provide greater navigation accuracy.
