Assignee: MEDTRONIC NAVIGATION, INC.
Field: Medical technology (Instruments)
Classification: CPC A  G | IPC A  G

Claim 13:
14. A method of performing a navigated procedure relative to a subject, comprising:
accessing a first image data of at least a region of interest of the subject;
tracking a reference point by tracking a first tracker assembly having at least (i) a first tracking device in a first coordinate system and (ii) a second tracking device in a second coordinate system, wherein the reference point is a common reference point between the first coordinate system and the second coordinate system;
registering a first image data coordinate system of the first image data to a navigation space based on the tracked reference point;
tracking a third tracking device in only one of the first coordinate system or the second coordinate system, wherein tracking the third tracking device in only one of the first coordinate system or the second coordinate system is correlated to the other of the first coordinate system or the second coordinate system due at least to the tracked common reference point;
associating the first tracker assembly with a first segmented portion in the first image data;
associating the third tracking device with a second segmented portion in the first image data;
indirectly tracking a portion of the subject illustrated as a third segmented portion in the first image data via tracking the first tracker assembly or the third tracking device without any tracking device directly associated with the third segmented portion;
displaying the first image data with a display device; and
updating the first image data at least by (i) changing a position of the first segmented portion or the second segmented portion based upon tracking the third tracking device in only one of the first coordinate system or the second coordinate system and (ii) changing a position of the third segmented portion by indirectly tracking the portion of the subject.
