Abstract
A method is presented to reconstruct the elastic modulus of soft tissu e based on ultrasonic displacement and strain images. Incompressible a nd compressible media are considered separately, Problems arising with this method, as well as applications to real measurements on gel-base d, tissue equivalent phantoms, are given. Results show that artifacts present in strain images can be greatly reduced using a hybrid reconst ruction procedure based on numerical solution of the partial different ial equations describing mechanical equilibrium of a deformed medium.
