    摘要: Methods and systems for the accuracy evaluation of an Image Guided Surgery system. One embodiment includes: identifying a position of a landmark in a three-dimensional image of an object; and overlaying a first marker on a reality view of the object according to registration data that correlates the three-dimensional image of the object with the object, to represent the position of the landmark as being identified in the three-dimensional image. In one embodiment, the reality view of the object includes a real time image of the object; a position of the landmark is determined on the object via a position determination system; and a second marker is further overlaid on the real time image of the object, to represent the position of the landmark as being determined via the position determination system.

    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. 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; and generating a virtual stereoscopic image showing the probe relative to the patient, according to the determined pair of virtual viewpoints.
