Title:
TISSUE PARAMETER DETECTION METHOD AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/121170
Kind Code:
A1
Abstract:
A tissue parameter detection method and system. The method comprises: controlling an excitation apparatus (2) to excite, in a tissue, N shear waves with different excitation characteristics by taking a pre-set time interval as a period, and controlling a first ultrasonic transducer (3) to transmit, to a tissue, an ultrasonic signal corresponding to each shear wave during each period; receiving an ultrasonic echo signal corresponding to each shear wave via the first ultrasonic transducer (3); according to the ultrasonic echo signal corresponding to each shear wave, respectively acquiring a propagation characteristic parameter of each shear wave; according to the propagation characteristic parameters of N shear waves with different excitation characteristics, obtaining a tissue parameter through calculation. By exciting N shear waves with different excitation characteristics, since a tissue has different responses to each shear wave, a more accurate tissue parameter can be obtained by measurement; thereby improving the precision and sensitivity of tissue parameter measurement.
