Limits on the contrast of strain concentrations in elastography

Ultrasound Med Biol. 1998 Oct;24(8):1215-9. doi: 10.1016/s0301-5629(98)00106-9.

Abstract

Using an analytic solution of the elasticity equation derived for a cylindrical inclusion, it is shown that the contrast of the strain concentrations is limited for both hard and soft lesions. This means that, beyond a given elastic modulus contrast, the strain concentrations remain virtually constant.
