  • Reconstruction method of organ vessel centerline
    Patent number: 11961187
    Abstract: The present invention relates to a method of producing a 3D centerline of an organ vessel from a plurality of 2D x-ray images. The method comprises the steps of producing a point-cloud of 3D points which represent intersecting and non-intersecting points between projection lines from the 2D images to their respective x-ray sources; fitting a compound curve to the points in the point-cloud of 3D points; removing outliers from the point-cloud; fitting a new compound curve to the remaining points in the point-cloud of 3D points; and repeating certain steps, wherein the resultant compound curve represents the 3D centerline of the organ vessel. The method minimizes reconstruction errors and produces an optimally-reconstructed 3D vessel skeleton.
