Abstract

It is well known that mechanical properties of tissues like elasticity and viscosity depend on factors such as age and pathology. For example, physicians use palpation for assessing the mechanical properties of tissues to detect tumors and other abnormalities. However, palpation provides non-quantitative, subjective information and is limited to accessible regions of the body. Therefore, there has been a consistent interest in developing quantitative, non-invasive techniques that distinguish tissues based on their mechanical properties such as elastic modulus1-11.
