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.

Abstract: An apparatus that allows the three-dimensional reconstruction of anatomic structures through the acquisition of two-dimensional echographic images produced by the real-time processing of signals reflected and/or scattered by said structures when these are hit by a beam of ultrasound generated, according to a predetermined scanning plane, by a piezoelectric transducer contained within an echographic probe. According to the invention, the scanning plane, in which the sector-scan transducer emits the beam of ultrasound, rotates through an angle of 180.degree., with intermediate angular increments having a predetermined amplitude and frequency, around the longitudinal axis of the probe, while the latter remains fixed relative to the examined anatomic structure, there being provided means for the actuation and the control of the rotation of the scanning plane.
