Surgical Navigation Systems And Methods For Detecting Localizer Motion

原文（中文）

Systems and methods for detecting localizer motion are provided. One such system is a surgical navigation system which includes a first tracker, a second tracker, a localizer, and one or more controllers. The localizer is configured to track the first tracker to generate first tracking data, and to track the second tracker to generate second tracking data. The one or more controllers are configured to receive the first tracking data and the second tracking data, calculate a relative motion of the first tracker based on the first tracking data, calculate a relative motion of the second tracker based on the second tracking data, compare the relative motions of the first and second trackers to one another, and detect a movement of the localizer based on the comparison.
