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

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