Abstract :
Elastography is a promising imaging technique that produces images termed elastograms which map the strain experienced by tissue elements subjected to a quasi-static compression. In this paper, we represent analytic expressions modeling the strain field for an inclusion and its background when a circular homogeneous inclusion attached to a homogeneous infinite medium which is subjected to a remote uniform uniaxial compression, and base on this model, we discuss on the potential of elastography technique in differentiating various tumors´ genera. We also represent some experimental results that imitate our results. Both the analytic relationships and the experimental results confirm that it is not reliable to make distinction between certain types of tumors through assessment of elastograms.
