Abstract
An in vivo source of compression is used to cause a bodily structure of interest to expand and contract. Ultrasound signals are incident and their echoes are processed by a strain processor. Resulting strain images are freed from noise caused by external sources of compression. A tissue stiffness index is calculated to obtain quantitative measure of stiffness.
