摘要： [A method of generating a multi-dimensional surface model of a geometric structure is provided. The method comprises acquiring a set of location data points comprising a plurality of location data points corresponding to respective locations on the surface of a region of the geometric structure. The method further comprises defining a bounding box containing each location data point of the set of location data points, and constructing a voxel grid based on the bounding box, wherein the voxel grid comprises a plurality of voxels. The method still further comprises extracting a multi-faceted surface model from certain of the plurality of voxels of the voxel grid using, for example, an alpha-hull approximation technique. The method may further comprise one or more of decimating and smoothing the surface of the multi-faceted surface model. A system comprising a processing apparatus for performing the aforedescribed method is also provided.

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： Electrical mapping system and methods are disclosed for modeling both unobstructed and obstructed portions of a catheter. An exemplary system includes a catheter body comprising a distal portion and a proximal portion, the catheter body supporting a plurality of electrodes electrically connected to an output device. The system also includes a rendering component operatively associated with the output device. The rendering component receives raw data from the plurality of electrodes and generates a plurality of images based on the raw data. Then the rendering component overlays the plurality of data images on one another to generate a three-dimensional image representing both the internal tissue and a visible portion of the catheter body. The system also includes an enhancement component which retrieves positional data for the catheter body and overlays a silhouette of at least one obstructed portion of the catheter body.

摘要： Disclosed herein are methods and systems for creating a complex model of the human anatomy (11). The anatomy may be modeled using multiple geometries. Generally, a plurality of line-of-sight models may be combined into a composite model. Multiple clouds (50) of points (40) may be used to create surface models which may then be merged into a common volume. The resulting composite model may include portions that are not within a line of sight of a mean center point of the composite model. The surface models may be modeled using polygons, including for example, triangles. Disclosed herein are also ways in which electrophysiology data and/or other information may be mapped from a measurement point to a point on the composite model.
