Basic principles and examples of elasticity imaging aresummarized. The chapter focuses on static ultrasonicmethods, and it discusses the advantages and limitationsof this approach in the context of dynamic methods andalternative imaging modalities from the literature. We re-view the physics of continuum deformations as a way toevaluate various experimental approaches. A ...
