Abstract:
A computer implemented method 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. A gradient field of a distance transformation is computed for the edge-detected dataset. A voxel data set corresponding to a centerline of the tubular structure is computed according to derivative of gradient field. A trajectory within the tubular structure is computed based on the centerline.

Claim (Index 15):
The system of  claim 14 , wherein the model generator is further programmed to generate a surface model of the tubular structure based on the centerline model, the system further comprising:\n a fusion engine programmed to generate a fused image data set that comprises the surface model superimposed on a graphical representation of the tubular structure, wherein the fusion engine is programmed to register the surface model with the graphical representation; a position calculator programmed to determine a position of a distal end portion of a steerable medical device within the tubular structure based on the fused image data set, a robotic system configured to control a position of the distal end portion of the steerable medical device within the tubular structure based on the position of the distal end portion of the steerable medical device and the computed trajectory.
