A method for measurement of the bladder wall nonlinear elasticity is presented. The method is based on acoustoelasticity modeling of the bladder tissue modulus of elasticity changes at different volumetric loading levels. At each loading volume, tissue strain is obtained from the real-time images. Using acoustic radiation force, a transient Lamb wave is excited on the bladder wall and shear elasticity...
Bladder is a complex organ and its proper function is closely tied to the mechanobiology of its multi-layer wall. Characterization of the bladder wall mechanical properties is crucial in diagnosis of diseases that can lead to lower tract infection and incontinence. Ultrasound bladder vibrometry has emerged as a noninvasive method for characterization of the bladder tissue elasticity using Lamb wave...
Elasticity values reported by shear wave elastography techniques for Breast tissue/mass are a combination of elasticity and viscosity at the frequency with peak shear wave energy; thus, resulting in overestimation of tissue elasticity. To better estimate shear elasticity and to understand the role of shear viscosity in suspicious breast masses at different frequencies, the frequency dispersion of...
The automotive domination in high-growth Asian conurbations is typically seen as the outcome of conventional market forces driven by income and aspirational consumer motivations. Proposed here is a more complex explanation, where path-dependent growth and associated positive feedback mechanisms underlie a staged process that evolves into a non-Pareto efficient form of market failure, inflicting a...
To provide the elderly with appropriate and timely caregiving in activities of daily life (ADL), it is desired for robots to have the capability of intention awareness (IA). Different from existing context-specific intention awareness (CSIA) approaches which are based on a limited and passive knowledge database, our approach, named ‘WebIA’, adopts a novel web query approach to establish a vast and...
