摘要：
Disclosed herein is a system and method for dynamic validation, correction of registration for surgical navigation during medical procedures on a patient which involves confirmation of registration between one or more previously registered virtual objects, such as surgical tools etc. in a common coordinate frame of a surgical navigation system and an operating room, and intra-operatively acquired imaging during the medical procedure in the common coordinate frame. The method includes displaying intra-operatively acquired imaging of the surgical field containing the one or more real objects corresponding to the one or more previously registered virtual objects, with the real objects being tracked by a tracking system. The method overlaying a virtual image containing the previously registered virtual objects onto the intra-operatively acquired imaging, from the point of view of the intra-operatively acquired imaging, and detecting for any misalignment between any one of the one or more previously registered virtual objects contained in the virtual image and its corresponding real object contained in the intra-operatively acquired imaging.
