This paper examined the availability of a method for calculating the "mean elastic constant" of tissue and its practical applicability. The error analysis for the elastic constant of tissue was obtained by theoretical and experimental methods. Its error depends on measured lengths from Computerized Tomograms (CT), Ultrasonograms (US), CT-values and their deviations. This method can be accurately applied to soft tissue and organs of 4 cm or more with an error of less than 20% in vivo with the exception of bone, lungs, and gas filled organs. The procedure we employed for obtaining the "mean elastic constant" by combining CT with US is presented.
