This proposed technique, called "Nonlinear Elasticity Mapping (NEM)", is an innovative approach to estimate (i.e., linear and nonlinear) elasticity to provide complementary and relevant information for identification and characterization of breast masses. The proposed technique includes imaging the (nonlinear) elasticity parameter in a quantitative manner and measuring two new and relevant parameters. These parameters, together with linear elasticity, are used to differentiate breast masses. The first parameter is the nonlinearity of the elasticity.
