Dynamic feature rich anatomical reconstruction from a point cloud |
摘要 |
3-dimensional cardiac reconstruction is carried out by catheterizing a heart using a probe with a mapping electrode, and acquiring electrical data from respective locations in regions of interest in the heart, representing the locations of the electrical data as a point cloud, reconstructing a model of the heart from the point cloud, applying a set of filters to the model to produce a filtered volume, segmenting the filtered volume to define components of the heart, and reporting the segmented filtered volume. |

1. A method, comprising the steps of:
inserting a probe into a heart of a living subject, the probe having a mapping electrode; urging the mapping electrode into contacting relationships with a tissue in plurality of regions of interest of the heart; acquiring electrical data from respective locations in the regions of interest; representing the locations of the electrical data as a point cloud; reconstructing a model of the heart from the point cloud; applying a set of filters to the model to produce a filtered volume, wherein the steps of reconstructing the model and applying the set of filters are performed iteratively using portions of the point cloud until a stop condition is met; segmenting the filtered volume to define components of the heart; and reporting the segmented filtered volume, wherein at least one of the above steps is implemented in computer hardware or computer software embodied in a non-transitory computer-readable storage medium. |
