Patent ID: 11911110
Assignee: MEDTRONIC NAVIGATION, INC.
Field: Medical technology (Instruments)
Classification: CPC A  G | IPC A  G

Claim 8:
9. A system to navigate a procedure relative to a subject, comprising:
a display device to display image data having a first segmented portion of the subject and a second segmented portion of the subject;
a first tracking system defining a first tracking space with a first coordinate system;
a second tracking system defining a second tracking space with a second coordinate system;
wherein at least one of the first tracking system or the second tracking system is operable to track a reference point associated with (i) a first tracking device trackable in the first coordinate system and (ii) a second tracking device trackable in the second coordinate system;
a third tracking device trackable in only the second coordinate system and correlated to the first coordinate system due at least to a registration of the first coordinate system and the second coordinate system, wherein the third tracking device is associated with the first segmented portion in the image data;
a fourth tracking device trackable in only the second coordinate system and correlated to the first coordinate system due at least to the registration of the first coordinate system and the second coordinate system, wherein the fourth tracking device is associated with the second segmented portion in the image data;
wherein at least one of the third tracking device or the fourth tracking device includes a trackable portion separable from a mount; and
a navigation processor system operable to:
register the image data coordinate system of the image data to a navigation space based on the reference point tracked by at least the first tracking system or the second tracking system; and
generate updated image data as an update to the image data, including changing a position of at least one of (i) the first segmented portion or the second segmented portion and (ii) a third segmented portion of the subject based upon a tracked change in position of the third tracking device or the fourth tracking device; and
generate an updated image based on the updated image data for display with the display device;
wherein changing the position of the third segmented portion is not based upon a tracked change in position with any tracking device configured to connect to the subject.
