Background, Motivation and Objective Soft tissue contains mobile fluid that creates a time-dependent and spatially-varying internal strain field under sustained compression [1], which may be imaged dynamically by repeated scanning with ultrasound (US). The resulting technique, known as poroelastography [2], allows the measurement of the product of the tissues aggregate modulus and permeability, HAk, a nd its P oissons r atio, ν [ 1]. The aim of this s tudy was to e valuate the potential of simultaneous d ynamic imaging withs hear wave elastography and strain elastography to separate the components of Hak, and therefore recover the k, independently of ν and Youngs modulus, E.
