THREE DIMENSIONAL SHEAR ELASTIC MODULUS IMAGING FOR MAMMOGRAPHIC SCREENING AND DIAGNOSIS.

摘要

The aim of our work is to develop and evaluate an US technique to quantitatively measure and image the shear modulus of soft tissues in 3D. Specifically, to design and evaluate algorithms which accurately measure 3D displacement vector field from sets of US images and then use these displacements to accurately and efficiently measure the shear modulus of the imaged material. To that end, we designed a phantom study to test the accuracy and resolution of our algorithms.
