Abstract: An optical tracking system for a medical equipment includes optical markers, optical sensors and a computing device. The optical markers are disposed on the medical equipment. The optical sensors optically sense the optical markers to respectively generate sensing signals. The computing device is coupled to the optical sensors for receiving the sensing signals, and comprises a surgical situation 3-D model. The computing device is configured to adjust a relative position between a virtual medical equipment object and a virtual surgical target object in the surgical situation 3-D model according to the sensing signals.

Abstract: A method for identifying and locating at least one nerve in a target region is disclosed. In the method, an image detector is used to scan the target region according to a predicted nerve trend from a nerve identification program and capture 2D cross-sectional images of subregions of the target region, and the nerve identification program is utilized to identify' whether the 2D cross-sectional images are captured of the target nerve. When the nerve identification program identifies the 2D cross-sectional images are the images of the target nerve, a 3D image showing a 3D nerve structure is constructed from the 2D cross-sectional images based on 3D image reconstruction technique.
