摘要： Methods and apparatuses to record and review a navigation process of image guided surgery. One embodiment includes recording a sequence of positional data to represent a position or position and orientation of a navigation instrument relative to a patient during a surgical navigation process. Another embodiment includes: tracking positions and orientations of a probe during a surgical navigation process; and recording the positions and orientations of the probe, the recording of the positions and orientations to be used to subsequently generate images based on preoperative images of a patient. A further embodiment includes: reading a recorded sequence of locations of a navigational instrument; reading recorded video; generating a sequence of views of three dimensional image data based on the recorded sequence of locations; and combining the sequence of views with corresponding frames of the recorded video.

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.

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.
