Abstract :
In the context of dynamic vascular elastography (DVE), this paper proposes an analytical model to simulate the diffraction of harmonic and transient plane shear waves by radially layered soft cylinders. The model is discussed and validated in vitro on mono and bi-layered coagulated blood inclusions buried within gelatin phantoms.
