Elastographic characterization of two viscoelastic phantoms using three techniques: Shear Wave Induced Resonance Elastography, Transient Elastography and Supersonic Shear Imaging

Elastographic methods are used to characterize mechanical properties of soft tissues. Phantom materials mimicking tissues are commonly used to evaluate performances of elastographic methods. In this context, two kinds of materials were used and, for each kind, a set of phantoms was manufactured in our laboratory with a large range of variation of their Young's modulus (E). Their modulus have been measured with three elastographic techniques based on the generation and measurement of shear waves (Shear Wave Induced Resonance Elastography, Transient Elastography and Supersonic Shear Imaging) in order to compare median and dispersion of the measured E values.
