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, the method comprising the procedure of 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 being associated with the 2D coordinate system, acquiring a plurality of MPS points, within the at least one tubular organ, the MPS points being associated with the MPS coordinate system, the MPS coordinate system being registered with the 2D coordinate system, extracting a 3D image model of the at least one tubular organ form a pre-acquired 3D image of the volume of interest, estimating a volumetric model of the at least one tubular organ from the 2D image and from the acquired MPS points, registering the 3D coordinate system 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.
