摘要：
1. Device (100), comprising: an ultrasonic transducer configured to (i) launch directed rays (104) into a medium (108), wherein each directed beam contains a focus of the directed beam, and is configured to generate a corresponding transverse wave (112) along the propagation path (156) through the medium； the ultrasonic transducer is further configured to (ii) emit tracking beams (116, 120, 124, 128, 132), obtain the corresponding reflected signals and measure in response to the emitted tracking beams and, respectively the existing received shear wave reflected signals caused by a shear in the medium at various locations in space along the propagation path of the corresponding shear wave； an existing shear-based weighing scheme (110) operably coupled to all tracking beams, wherein the existing shear-based weighing scheme is configured to (i) use shear under the action of a shear wave, measured at different locations along the propagation path (156) to determine center of mass (COM) time values for each of the different locations of space, and time values are weighted based on the shift of the time value of the corresponding shift curve, which The first corresponds to the time associated with the image that determines the shift, and (ii) the calculation, in response to the first sum (238) divided by the second sum (242), of the shifts used in weighing, providing the weighted average time of arrival of the corresponding shear wave in the corresponding a place from different locations of space,1. Устройство (100), содержащее:ультразвуковой преобразователь, выполненный с возможностью (i) запуска направленных лучей (104) в среду (108), причем каждый направленный луч содержит фокус направленного луча, и выполнен с возможностью создания соответствующей поперечной волны (112) вдоль траектории распространения (156) сквозь среду；ультразвуковой преобразователь дополнительно выполнен с возможностью (ii) испускания лучей слежения (116, 120, 124, 128, 132), получения соответствую
