A description is given of a device and a method for reconstructing the three-dimensional structure of blood vessels or other structures. The method comprises the stages of: obtaining at least three images of the blood vessels to be reconstructed, each of said images showing reference points which permit the determination of a matrix (T) which describes the geometric projections associated with each image; identifying, by means of said three images, a starting point for the tracing of a center line of a blood vessel; tracking the center line of the blood vessel to an end point; determining the cross-sectional dimension of said blood vessel at a plurality of points of the center line; reconstructing the three-dimensional image of the blood vessel from said cross-sectional dimensions and said center line.

Abstract
A description is given of a device and a method for reconstructing the three-dimensional structure of blood vessels or other structures. The method comprises the stages of: obtaining at least three images of the blood vessels to be reconstructed, each of said images showing reference points which permit the determination of a matrix (T) which describes the geometric projections associated with each image; identifying, by means of said three images, a starting point for the tracing of a center line of a blood vessel; tracking the center line of the blood vessel to an end point; determining the cross-sectional dimension of said blood vessel at a plurality of points of the center line; reconstructing the three-dimensional image of the blood vessel from said cross-sectional dimensions and said center line.File | Dimensione | Formato | |
