摘要： A method of repairing a three dimensional surface mesh model to be watertight and manifold generally includes identifying a plurality of hole edges in the surface mesh model, selecting one of the hole edges, creating a cycle of hole edges that defines a hole in the surface mesh model, converting the cycle of hole edges into two or more cycles of exactly three edges each, and adding a triangular facet to the surface mesh model for each of the cycles of exactly three edges. The process may be repeated until the model is substantially watertight. Non-manifold vertices may be repaired by selecting a vertex of the model, identifying a number of independent cycles of triangular facets sharing the selected vertex, and redefining the selected vertex for at least all but one of the number of independent cycles. This process may be repeated until the model is manifold.

摘要： A system for determining a location of an electrode of a medical device ( e.g. , a catheter) in a body of a patient (11) includes a localization block 32 ()for producing an uncompensated electrode location (33), a motion compensation block (34) for producing a compensation (signal 35) ( i.e ., for respiration, cardiac, etc.), and a mechanism (37) for subtracting the compensation signal (35) from the uncompensated electrode location (33). The result is a corrected electrode location (38) substantially free of respiration and cardiac artifacts. The motion compensation block (34) includes a dynamic adaptation feature which accounts for changes in a patient's respiration patterns as well as intentional movements of the medical device to different locations within the patient's body. The system further includes an automatic compensation gain control (36) which suppresses compensation when certain conditions, such as noise or sudden patch impedance changes, are detected.

摘要： A method for registering a catheter navigation system to a three-dimensional image generally includes obtaining a three-dimensional image including position information for a plurality of surface points on a part of a patient's body, using a catheter navigation system to place a tool at a location on the surface of the patient's body, measuring position information for the surface location, identifying a corresponding location on the image, associating position information for the surface location and the location identified on the image as a fiducial pair, and using at least one fiducial pair to generate a mapping function. The mapping function transforms points within the coordinate system of the catheter navigation to the coordinate system of the three-dimensional image such that, for each fiducial pair, the mapping error is about zero. Suitable warping algorithms include thin plate splines, mean value coordinates, and radial basis function networks.
