Understanding contrast mechanisms and identifying discriminating features is at the heart of diagnostic imaging development. This report focuses on how pH influences the viscoelastic properties of biopolymers to better understand the effects of extra

It has been estimated that over 62 million tendon and ligament injuries occur every year. The failure rate for these injuries can be despairingly high, such as 94% in the case of rotator cuff injuries. One possible cause for these failures is the ina

Virtually every area of ultrasonic imaging research requires accurate estimation of the spatiotemporal impulse response of the instrument, and yet accurate measurements are difficult to achieve. The impulse response can also be difficult to predict n

Quantitative ultrasound (QUS) techniques make use of frequency-dependent information from backscattered echoes normally discarded in conventional B-mode imaging. Using scattering models and spectral fit methods, properties of tissue microstructure ca

Ultrasonic elasticity imaging enables visualization of soft tissue deformation for medical diagnosis. Our aim is to understand the role of flow-dependent and flow-independent viscoelastic mechanisms in the response of biphasic polymeric media, includ

The viscoelastic response of hydropolymers, which include glandular breast tissues, may be accurately characterized for some applications with as few as 3 rheological parameters by applying the Kelvin-Voigt fractional derivative (KVFD) modeling appro

The poro-viscoelastic (PVE) response of tissues or hydropolymers may be accurately modeled with as few as three parameters using the Kelvin-Voigt fractional derivative approach. We propose to image these parameters for simulated and experimental imag
