Abstract
This computer-implemented method allows assessing the shear elasticity modulus of a flexible tube, such as a blood vessel. In the field of medicine, this allows assessing whether a blood vessel is at risk of breakage or tearing. In the case of an artificial tube to be implanted in a patient's body, this allows verifying that this tube is compatible with the patient's body. The method includes the following further steps: a) obtaining () a first dataset relating to spatiotemporal deformations of the tube; b) detecting and storing () a wall inner surface of the tube and its diameter (D); c) identifying () a number of transverse sections (Sij) of the tube; d) computing () an average particle velocity (Vij) over each section; e) computing () a wave propagation speed (C) of an antisymmetric wave (W); f) based on the wave propagation speed (C) and on the diameter (D), assessing () the shear elasticity modulus (μ) of the tube.
