摘要
A method for registering a three dimensional (3D) coordinates system with a Medical Positioning System (MPS) coordinate system and with a two dimensional (2D) coordinate system, includes acquiring at least one 2D image of a volume of interest, the volume of interest including at least one tubular organ within the body of a patient. The 2D image is associated with the 2D coordinate system, and a plurality of MPS points is acquired, within the at least one tubular organ. The MPS points are associated with the MPS coordinate system, the MPS coordinate system being registered with the 2D coordinate system. A 3D image model is extracted of the at least one tubular organ form a pre-acquired 3D image of the volume of interest. A volumetric model of the at least one tubular organ from the 2D image is estimated and from the acquired MPS points, the 3D coordinate system is registered with the MPS coordinate system and with the 2D coordinate system by matching the extracted 3D image model and the estimated volumetric model of the at least one tubular organ.
