متن کاملComplex Shear Modulus Reconstruction Using Ultrasound Shear - Wave Imaging
Many pathological processes in tissues are recognized by morphological changes that reflect alterations of the soft tissue mechanical properties. Ultrasound shear-wave imaging can provide quantitative information about soft tissue mechanical properties, specifically the complex shear modulus. Advancing this field has the potential to bridge molecular, cellular, and tissue biology and to influen...
متن کاملTorsion pendula with electromagnetic drive and detection system for measuring the complex shear modulus of liquids in the frequency range 802500 Hz
" An apparatus for the measurement of liquid complex shear viscosity in the frequency range 80-2500 Hz, with the use of a torsion pendulum operating in forced oscillation, is described. The drive and detection system consists of a magnet inside the pendulum, two excitation and two measuring coils. The determination of the complex shear viscosity is based on the measurement of the resonance freq...
متن کاملDetermination of the viscoelastic shear modulus of poly(isobutylene)/solvent systems using thickness-shear mode quartz resonators
Determination of the storage modulus, G', loss modulus, G", and, consequently, the shear moduli, G (G = G' + jG" ), of polymer and polymer/solvent systems was conducted in this study using a thickness-shear mode (TSM) quartz resonator. The polymer poly(isobutylene) was spin-coated as a film of a few microns thickness on the surface of the TSM device and, upon inducing oscillation of the device ...
