Abstract: Ultrasound elasticity imaging is a promising method that may eventually allow early detection of many tissue pathologies. The quasi-periodic regularly structure of tissue peaks in the power cepstrum of ultrasonic backscatter. A method to estimate tissue strain based on mean scatter spacing, and distribution of Young's modulus of the soft tissue with external stress is addressed whose axis resoluti on is 2.5 mm and latteral resolution is 1.5 mm. Some aspects which should be considered in elasticity measurement of soft tissue are discussed.
Keywords: Young's modulus, mean scatter spacing, ultrasound elasticity imaging.
