摘要： A method of registering two or more localization systems 8 utilizing unique coordinate frames A and B to a common coordinate frames includes measuring position information for one or more reference locations r in each coordinate frame (Ar and Br). For each reference location, a fiducial grouping is created from the respective position measurements (Ar, Br). The fiducial groupings are used to generate a mapping function f that transforms position measurements expressed relative to the second coordinate frame B to the first coordinate frame A. The mapping function f is defined such that a distance between f(Br) and Ar is about zero for each reference location r. Each localization system 8 may also measure position information for a respective fixed reference localization element. Divergence between these fixed reference localization elements in the common coordinate system may be used to monitor, signal, and correct for anomalies such as dislodgement and drift.

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.

摘要： A method of operating a positioning system 10 by registering a first coordinate system 14 of a first positioning system 12 in a second coordinate system 18 of a second positioning system 16 includes determining an interpolation function configured to register the first, non-orthonormal coordinate system in the second, orthonormal coordinate system. Fiducial pairs are collected by the respective positioning systems 12, 16, each of which contain a respective coordinate in the respective coordinate system 14, 18, both of which refer to the same physical point in three dimensional space. Establishing a working interpolation function involves an analysis of the fiducial pairs using a thin-plate spline algorithm. The method further includes repeatedly obtaining a first coordinate in the first coordinate system 14 and determining a corresponding second coordinate in the second coordinate system 18 in accordance with the interpolation function.

摘要： A method for transforming solid, three dimensional image data into three dimensional surface data first smoothes the surface of the solid image by removing (210) extraneous voxels both attached to main surface of the solid image as well as extraneous voxels about the main image before the surface transformation. Once the solid image is transformed into a surface image, the method again cleans the surface by removing (840) any significantly spiked structures that appear out of place when considered with respect to the surrounding topography. The amount of data required to render the surface image is reduced by removing (130) surface facets that fall within a planar threshold of the surrounding topography. The topography is also compressed in local areas to bring the topography toward a median level. The method may further cycle (140) to attempt to reduce additional surface facets that may fall now within the threshold limit.
