Acoustic Field Characterization of Medical Array Transducers Based on Unfocused Transmits and Single-Plane Hydrophone Measurements
Torben Marhenke,Sergio J. Sanabria,Bhaskara Rao Chintada,Roman Furrer,Jürg Neuenschwander,Orcun Goksel +5 more
TL;DR: It is shown that source fields can be reconstructed at single crystal level at wavelength resolution, based on far-field measurements, and re-radiation method based on the Rayleigh–Sommerfeld integral to medical imaging array characterization is explored.
Journal ArticleDOI
Rotation Elastogram Estimation Using Synthetic Transmit-aperture Technique: A Feasibility Study.
TL;DR: The results demonstrate that the contrast appeared in RE only in the case of loosely bonded inclusion, and the quality of RE improved considerably by employing the Synthetic Transmit Aperture technique.
Journal ArticleDOI
Spectral Quantification of Nonlinear Elasticity Using Acoustoelasticity and Shear-Wave Dispersion
TL;DR: This work characterize the nonlinear parameters of tissue as a function of excitation frequency by utilizing both AE and SSWE together, and results from phantom and ex vivo porcine liver experiments demonstrate the feasibility of measuring frequency-dependent non linear parameters using the proposed method.
Proceedings ArticleDOI
Acoustoelasticity Analysis of Shear Waves for Nonlinear Biomechanical Characterization of Oil-Gelatin Phantoms
TL;DR: In this paper, the nonlinear relationship of shear modulus as a function of applied stress/strain can be deduced using acousto-elasticity analysis using two sets of oil-gelatin phantoms, one set representing steatotic stages while the other set emulating additional biomechanical changes following the onset of fibrotic processes in the liver.
Journal ArticleDOI
A Novel Elastographic Frame Quality Indicator and its use in Automatic Representative-Frame Selection from a Cine Loop
TL;DR: The results indicate that the automatic frame selection method described here may provide an objective way to select a representative frame while saving time for the radiologist.
