A surgical hardware and software monitoring system and method allows for surgical planning while the patient is available for surgery, for example while the patient is being prepared for surgery so that the system may model the surgical site. Tracker obtains image information, with controller configured to spatially relate image information with previously obtained scan data. Fiducial reference is configured for removably attaching to a location proximate a surgical site. The fiducial reference is observable by the tracker so that software of the controller determines three-dimensional location and orientation based on scan data and image data of the surgical site, spatially relating the image information to the scan data to determine the three-dimensional location and the orientation of the fiducial reference. In one embodiment, the model may be used to track contemplated surgical procedures and warn the physician regarding possible boundary violations that would indicate an inappropriate location in a surgical procedure. In another embodiment, the monitoring system may track the movement of instruments during the procedure and in reference to the model to enhance observation of the procedure. In a further embodiment the monitoring system can be used to model and track the changes in the surgical site itself.
A surgical monitoring system comprising a tracker for obtaining image information, a controller configured to spatially relate image information with previously obtained scan data characterized by a fiducial reference configured for removably attaching to a location proximate a surgical site, the fiducial reference being observable by the tracker so that software of the controller determines three-dimensional location and orientation based on scan data and image data of the surgical site, and spatially relates the image information to the scan data to determine the three-dimensional location and the orientation of the fiducial reference.
A surgical monitoring system comprising a fiducial reference adapted to be fixed to an area of surgical patient, a marker attached to an implement in a predetermined orientation, a tracker able to determine the position and orientation of the one or more markers, characterized in that at least one of said marker and said tracker are connected to the fiducial reference in a fixed relative position, and further characterized by a computer system having a scan of the patient with the fiducial reference fixed to the area of surgical patient, said computer system coupled to said tracker and including a processor with memory and a software program having a series of instructions when executed by the processor determines the relative position and orientation of the marker based on information from said tracker, and relates the current arrangement of the implement in relation to the scan data;
A surgical monitoring system comprising a fiducial reference capable of attaching to a location proximate to a surgical site, said fiducial reference being perceptible on a scan;
A method for relating in real time the three-dimensional location and orientation of a surgical site on a patient to the location and orientation of the surgical site in a scan of the surgical site, the method characterized by removably attaching a fiducial reference to a fiducial location on the patient proximate the surgical site;
A method for tracking in real time changes in a surgical site, the method characterized by removably attaching a multi-element fiducial reference to a fiducial location on the patient proximate the surgical site, the multi-element fiducial reference comprising a plurality of pattern segments individually locatable based on scan data;
A method for real time monitoring the position of an object in relation to a surgical site of a patient, the method characterized by removably attaching a fiducial reference to a fiducial location on the patient proximate the surgical site;
