System and method for hybrid tracking in surgical navigation
First Claim
1. A medical tracking system, said system including:
- a plurality of tracking technologies employed during a medical procedure;
a reconciler determining an active tracking technology during said procedure, said active tracking technology including at least one of said tracking technologies;
a switch activating said active tracking technology, wherein said switch activates said active tracking technology over a period of time such that a visual representation corresponding to said active tracking technology becomes more visible as a visual representation corresponding to said deactivated tracking technology becomes less visible over said time period; and
wherein each tracking technology has a metric associated therewith, and, when a metric associated with a deactivated tracking technology exceeds a metric associated with an activated tracking technology, said reconciler directs said switch to activate the tracking technology with the greater metric and deactivate the tracking technology with the lesser metric.

Abstract
A system and method for hybrid tracking in surgical navigation is disclosed. A plurality of tracking technologies is used in a medical procedure where a reconciler determines an active tracking technology. The reconciler determines the active tracking technology during the medical procedure. A switch may then activate one or more tracking technologies. The determination of which technology or technologies are to be activated may be based, for example, on metrics measured by each of the technologies, such as an accuracy measurement. In addition, a display may present representations based on at least data obtained by one or more of the tracking technologies. The switch may employ weighted switching to gradually switch the display of a first representation corresponding to a first tracking technology to the display of a second representation corresponding to a second tracking technology, where the first technology is deactivated and the second technology is activated.

10. A method for hybrid tracking in medical navigation system, said method including:
-
employing a plurality of tracking technologies for use during a medical procedure; determining an active tracking technology during said procedure, said active tracking technology including at least one of said tracking technologies; activating said active tracking technology, wherein said activating step occurs over a period of time such that a visual representation corresponding to said active tracking technology becomes more visible as a visual representation corresponding to said deactivated tracking technology becomes less visible over said time period; and wherein each tracking technology has a metric associated therewith, and, when a metric associated with a deactivated tracking technology exceeds a metric associated with an activated tracking technology, said activating step includes activating the tracking technology with the greater metric and deactivating the tracking technology with the lesser metric. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
