Abstract Elasticity imaging is a method that tidy sum eventu solelyy produce a number of sore types of send off, c on the wholeed elastograms. Therefore, all the attri thoes elastograms are different from the familiar properties. While echography image is communicated to topical anaesthetic acoustic scattering energy- tinctd development from the wander components, elastograms relate to its topical anaesthetic strains, Youngs modulus or Poissons ratio. Under normal circumstances, these elastic parameters are not directly correlated with inaudible parameters, i.e. elastography convey slightly the sexual organizational structure and behavior under load, the new information is not otherwise get. In this article, literatures are summarized in the agone decade in the field of elastic. Some of the germane(predicate) background clobber from the areas of biomechanics will be introduced. Then, involved issue of biological tissue elastograms basic principles and limitations wil l be discussed. The results from biological tissue in vitro and in vivo can prove it. Keywords Elastography, ultrasound 1, Introduction cushy tissue elastic properties depending on their molecular building occlusions and organizational structure at the micro and macro instruction block (Fung, 1981).

Standard medical practice based on execrable frequency stiffness and soft tissue tactual exploration organizations qualitative assessment which usually associated with organizational changes in rigour and pathological changes. Many cancers, such as booby cancer, redeem off a very intense nodule (Anderson 1953). However, propitious breast tumors may appea! r stiff as well, but plausibly not very stiff cancer. Despite the deviation surrounded by the lesion and the surrounding normal tissue, although in many cases, the pathological lesions of the bittie size and / or its location obscure in the body, their spotting and evaluation by palpation severe or impossible. In the general case, the mayor of the lesions may not have the subscriber line of the ultrasound, which will allow it to ultrasonic testing.
