Title:  Algorithms and Modeling for Successful Imaging of Shear Stiffness 
in Tissue: The goal is a new medical diagnostic tool.

The doctors' palpation exam has inspired a collection of inventive
experiments that enable imaging of shear stiffness in tissue, the tissue
property that, for centuries, doctors have felt in order to make
diagnoses.  In this talk, three of these experiments, as well as the rich 
data subsets that are produced, will be described.  A succession of
algorithms will be presented along with the image improvements and
analysis results.  Applications include breast and prostate cancer.
Current experimentalists with whom we collaborate are:  Dr. Richard
Ehman, Mayo Clinic; Mathias Fink, ESPCI, Paris; and Dr. Kevin Parker at
the University of Rochester.
