摘要:
Disclosed are a method and a device for elasticity detection. The method comprises: controlling an excitation device (2) to periodically excite N shear waves in a tissue at a preset time interval and controlling an ultrasonic transducer (3) to transmit ultrasonic waves (101) to the tissue, where the excitation device and the ultrasonic transducer are maintained in contact with a surface of the tissue; receiving, by the ultrasonic transducer (3), an ultrasonic echo signal (102) corresponding to each of the shear waves; acquiring a propagation characteristic parameter (103) of each of the shear waves according to the ultrasonic echo signal corresponding to each of the shear waves; calculating an elasticity parameter of the tissue (104) according to propagation characteristic parameters of the N shear waves and a tissue density of the tissue. The excitation device (2) and the ultrasonic transducer (3) are maintained in contact with the surface of the tissue without manually locating the excitation device (2) several times on the surface of the tissue, thereby ensuring that the N shear waves are excited in respect to the same position, which is helpful to ensure the accuracy of the final elasticity parameter detection result.
