Automated centerline extraction method and generation of corresponding analytical expression and use thereof
Abstract:
A computer implemented method (350) for determining a centerline of a three-dimensional tubular structure is described. The method includes providing an edge-detected data set of voxels that characterize a boundary of the tubular structure according to a three-dimensional voxel data set for the tubular structure (360). A gradient field of a distance transformation is computed for the edge-detected dataset (380). A voxel data set corresponding to a centerline of the tubular structure is computed according to derivative of gradient field (390).
