Abstract

Basic principles and examples of elasticity imaging are summarized. The chapter focuses on static ultrasonic methods, and it discusses the advantages and limitations of this approach in the context of dynamic methods and alternative imaging modalities from the literature. We review the physics of continuum deformations as a way to evaluate various experimental approaches. A general strategy for the design of ultrasonic elasticity imaging algorithms for static deformations is also described. The objective is to summarize and critically assess a subset of current approaches to this exciting new field.
