From times immemorial manual palpation served as a source of information on the state of
soft tissues and allowed detection of various diseases accompanied by changes in tissue …

Sonoelastography is a modern ultrasound method, which enables the representation of
tissues and organs with the evaluation of their elasticity,“stiffness”. The principle of …

Inverse modeling for computing a high-dimensional spatially-varying property field from
indirect sparse and noisy observations is a challenging problem. This is due to the complex …

Viscoelasticity of soft tissue is often related to pathology, and therefore, has become an
important diagnostic indicator in the clinical assessment of suspect tissue. Surgeons …

In recent years, several new techniques based on the radiation force of ultrasound have
been developed. Vibroacoustography is a speckle-free ultrasound based imaging modality …

This work presents a thorough theoretical and numerical analysis of the elasticity imaging
inverse problem of tumor identification in the soft tissue of the human body. Beyond the …

This paper presents a methodology for the inverse identification of linearly viscoelastic
material parameters in the context of steady-state dynamics using interior data. The inverse …

Elastographic techniques are new ultrasound-based imaging techniques developed to
estimate tissue deformability/stiffness. Several ultrasound elastographic approaches have …

The traction exerted by a cell on the extra-cellular matrix (ECM) is critical to understanding
and manipulating important biological processes such as stem cell differentiation, cancer …

The primary objective of this work is to study the elasticity imaging inverse problem of
identifying cancerous tumors in the human body. This nonlinear inverse problem not only …
