METHODS AND APPARATUSES FOR STEREOSCOPIC IMAGE GUIDED SURGICAL NAVIGATION

摘要

Methods and apparatuses to generate stereoscopic views for image guided surgical navigation. One embodiment includes transforming a first image of a scene into a second image of the scene according to a mapping between two views of the scene. Another embodiment includes generating a stereoscopic display of the scene using a first image and a second image of a scene during a surgical procedure, where a position and orientation of an imaging device is at least partially changed to capture the first and second images from different viewpoints (821, 823). A further embodiment includes: determining a real time location of a probe relative to a patient during a surgical procedure; determining a pair of virtual viewpoints according to the real time location of the probe (803); and generating a virtual stereoscopic image showing the probe relative to the patient, according to the determined pair of virtual viewpoints.
