    摘要: The present invention involves a surgical monitoring system and method for modeling surgical procedures. A multi-element fiducial reference pattern observable by a tracker may be transferred directly to the skin proximate the surgical site, either through a stencil as a radio-opaque ink pattern or via transfer tape, or may be applied in prepared form on a surgical incise film. Alternatively the surgical incise film may be applied over the surgical site and the inked reference pattern applied to the film before surgery. A controller determines the three-dimensional location and orientation of the surgical site by comparing the position and orientation of the reference pattern in a prior scan with the position and orientation of the reference pattern in image information about the surgical site obtained from the tracker. The system may track the movement of instruments relative to the surgical site, or may be used to track changes in the surgical site itself.

    摘要: A three-dimensional position and orientation tracking system comprises one or more pattern tags, each comprising a plurality of contrasting portions, a tracker for obtaining image information about the pattern tags, a database with geometric information describing patterns on pattern tags; and a controller for receiving and processing the image information from the tracker, accessing the database to retrieve geometric information, and comparing the image information with the geometric information. The contrasting portions are arranged in a rotationally asymmetric pattern and at least one of the contrasting portions on a pattern tag has a perimeter that has a mathematically describable curved section. The perimeter of the contrasting portion may comprise a conic section, including for example an ellipse or a circle. The tracking system can be implemented in a surgical monitoring system in which the pattern tags are attached to tracking markers or are themselves tracking markers.
