TRACKING CAS SYSTEM |
摘要 |
A computer-assisted surgery system for tracking an object during surgery comprises a first tracker device and a second tracker device secured to different parts of the object. The first and the second tracker device are secured to the object separately in such a way that a geometrical pattern is defined with trackable elements from the first tracker device and from the second tracker device. A tracking system has a sensor unit tracking the trackable members. A calibration unit defines a geometrical pattern from the trackable members. A pattern identifier identifies the geometrical pattern. A position and orientation calculator calculates a position and orientation of the geometrical pattern The tracking system calculates position and orientation of the object as a function of the position and orientation of the geometrical pattern and of object/geometrical pattern relation data gathered during surgery. |
