You improve erasutogurahui measurement, strain or physical quality and in order to acquire the direct measurements of initial load, you are possible the fact that it models fluctuation of the acoustic quality which is while soft section organizing of organism organization and the like, as function of the strain.エラストグラフィ測定を改善し、歪又は物質特性及び初期応力の直接測定を取得するために、生体組織等の軟部組織内の音響特性の変動を、歪の関数としてモデル化することができる。
