Mechanical characterization of living tissues and organs are of interest because information on their viscoelastic properties in the presence of diseases can affect therapy planning. This article proposes the Dynamic Micro-Elastography (DME) method to characterize elasticity and viscosity parameters from the acoustical properties (velocity and attenuation) of monochromatic and transient shear waves...
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.
Staging mechanical properties of deep vein thrombi (elasticity and viscosity) can be of importance for therapy planning because the compactness of a blood clot impacts the efficiency of thrombolysis drugs. This article proposes the dynamic vascular elastography (DVE) method to solve this problem. It consists to retrieve viscoelastic parameters of 8-mm diameter blood clot cylindrical inclusions from...
Tissue-mimicking phantoms are very useful in the field of tissue characterization and essential in elastography for the purpose of validating motion estimators. This study is dedicated to the characterization of polyvinyl alcohol cryogel (PVA-C) for these types of applications. A strict fabrication procedure was defined to optimize the reproducibility of phantoms having a similar elasticity. Following...
