Reduction of heart motion artifacts in thoracic CT imaging

摘要

The invention relates to a system for adapting a plurality of model meshes to a plurality of image data. The system has a registration unit for registering the plurality of model meshes with the plurality of image data on the basis of a computation of a registration transformation for transforming the plurality of model meshes, and an adaptation unit for adapting the plurality of registered model meshes to the plurality of image data on the basis of a computation of locations of mesh vertices of the plurality of model meshes. The described system is capable of reducing motion artifacts in tomographic images computed from data acquired at a plurality of different cardiac cycle phases.
