METHOD FOR ENHANCING SHEAR WAVE IMAGING BASED ON ACOUSTIC VORTEX

Abstract: a method for enhancing shear wave imaging based on an acoustic vortex includes the following steps. an ultrasonic beam in an acoustic vortex waveform is transmitted to a target tissue through an ultrasonic transducer. an original wave source generated by the ultrasonic beam is sensed through the target tissue. the original wave source forms a shear wave source in a unit periodicity. the at least one shear wave source responds to generate a constructive interference shear wave source. a shear wave is generated through the constructive interference shear wave source. tissue characteristic information is obtained based on the shear wave imaging. an image of a displacement generated by the shear wave is drawn through the tissue characteristic information.
