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

Standard medical practice based on crushed frequency stiffness and soft tissue tactual exploration organizations qualitative assessment which usually associated with organizational changes in rigourousness and pathological changes. Many cancers, such as booby cancer, stomach off a very intense nodule (Anderson 1953). However , propitious breast tumors may appear stiff! as well, but plausibly not very stiff cancer. Despite the rest surrounded by the lesion and the surrounding normal tissue, although in umteen cases, the pathological lesions of the bittie size and / or its location mystical in the body, their spotting and evaluation by palpation rugged 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.
