Claim One:
1. A method of refining a model comprising: acquiring a two-dimensional echocardiogram from a catheter located within a subject; acquiring, from a plurality of position detectors associated with a distal portion of the catheter, a position and orientation of the catheter associated with the acquired two-dimensional echocardiogram; acquiring a three-dimensional anatomical model from the subject, the three dimensional model including one or more mapping points within a three dimensional model space; and using a processor to: relate the two-dimensional echocardiogram and the associated position and orientation of the catheter to the one or more mapping points of the three-dimensional anatomical model; determine a degree of influence value for the one or more mapping points; display the one or more mapping points with a visual attribute that corresponds to the determined degree of influence value; and refine the three-dimensional anatomical model based on the visual attribute; wherein using the processor to determine a degree of influence value for the one or more mapping points includes: determining a confidence value for the model; removing at least one of the one or more mapping points from the model; and calculating a change in the confidence value of the model attributable to the at least one removed point.
