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.
