  "abstract": "The measurement of guided wave propagation is an effective approach for evaluating arterial wall stiffness. A more comprehensive characterization of viscoelastic material properties could yield more informative biomarkers; however, this additionally requires estimation of wave attenuation. Furthermore, spatially local estimation is necessary for localized pathologies, such as atherosclerotic plaques. To this end, we propose an original two-stage high-resolution method to recover local viscoelastic properties from guided waves in artery-like soft tubes. First, the local frequency-wavenumber dispersion relation including losses is estimated using a high-resolution complex wavenumber identification method. Second, assuming a fractional Kelvin-Voigt rheological model for the tube wall, we estimate the viscoelastic material parameters by fitting the dispersion relation computed with a spectral element method to this estimate. We experimentally validate the proposed approach on flexural wave propagation along water-filled soft tubes, measured with a high-speed camera coupled with digital image correlation. Owing to the high resolution of the method, the axial modulus variation of a graded phantom is recovered. Finally, a Cramér-Rao analysis indicates that the complex wavenumber estimator operates near its theoretical limit, and reveals why local attenuation is intrinsically difficult to recover.",
