Recently, several researchers have investigated the potential of the use of acoustic radiation force for imaging the mechanical properties of tissue. However, these methods have some problems as to safety and the spatial resolution. Therefore, an alternative ultrasonic remote actuation and measurement method is proposed in this paper, in which the intensity of the applied continuous ultrasonic wave is suppressed to be lower than the safety guideline (1 W/cm 2 ) recommended by the Japan Societydoi:10.1143/jjap.42.4608 fatcat:sx7532utvzaa3nzmggpuh5mloe
