Abstract

The invention discloses a shear wave speed measurement method, device and system. The method comprises the steps of obtaining multiple echo information reflected by a to-be-detected soft tissue region aiming at ultrasonic pulse detection wave beams which are transmitted for many times, wherein shear wave propagation exists in the to-be-detected soft tissue region; according to the multiple echo information, respectively determining the wave speeds of shear wave between preset any two scan lines in the soft tissue region, and determining the weight of each wave speed according to the distance of two scan lines corresponding to each wave speed, wherein the longer the distance of two scan lines corresponding to each wave speed is, the larger the weight of the wave speed is; carrying out weighted average on all the wave speed according to the weight of each wave speed, so as to obtain the propagation speed of the shear wave in the soft tissue region. By using the shear wave speed measurement method, the measurement accuracy and reliability of the propagation speed of the shear wave in soft tissue are improved.

Description

technical field [0001] The present invention relates to the technical field of soft tissue lesion analysis, and more specifically relates to a shear wave velocity measurement method, device and system. Background technique [0002] Shear wave elastography based on acoustic radiation force is an ultrasound elastography technique for evaluating tissue elasticity, which is widely used in the analysis and diagnosis of human tissue lesions. The principle of shear wave elastography technology based on acoustic radiation force is: after the probe emits ultrasonic pulses to the soft tissue of the organism, under the action of shear stress, the soft tissue in a specific area will vibrate, thereby generating shear waves. Since the elasticity of biological soft tissue has a certain relationship with the velocity of shear wave, the elasticity of soft tissue can be analyzed by detecting the velocity of shear wave, so as to determine whether there is a soft tissue lesion.
