Abstract :
An effective method in static elastography for improving the nonuniformity of stress applied by the shape of a transducer head is to insert a damper between the tissue being analyzed and the transducer head. In this study, the optimal values were obtained for two parameters of the damper: the Young´s modulus and the damper thickness. An effective damper shape was also determined through structural analyses.
