Abstract
This paper proposes a method of measuring and visualizing the elasticity distribution of the human soft tissue to detect tumors or cancers which have been difficult to diagnose in conventional medical ultrasonic B-mode images. To measure the stiffness of soft tissue, first, pressure is applied to deform the tissue being imaged, and then the amount of mechanical displacement is determined from correlation coefficients obtained from ultrasonic data downconverted into the baseband. We confirmed the feasibility of imaging tissue stiffness by computer simulation and experiment.
