Three Dimensional Ultrasound Elasticity Imaging

摘要

The aim of our work is to develop and evaluate an ultrasound (US) technique to quantitatively measure and image the shear modulus of soft tissues in three dimensions (3D). The intended application of our work is the detection and characterization of breast tissue lesions, via elasticity imaging (EI), to improve the specificity of breast cancer screening. To that end, we have designed and characterized algorithms which 1) provide 3D motion estimates from 3D US images and 2) solve the 3D inverse problem to recover shear elastic modulus. The size and contrast accuracy of the reconstructed modulus distributions in tissue mimicking phantoms are presented.
