一种用于剪切波成像的超声换能器阵列探头(10)具有超过剪切波诊断成像系统的发射信道的数量的若干换能器元件。探头包括开关矩阵或多路复用器(60)，其将发射波束形成器(18)的信道选择性地耦合到阵列的多个剪切波孔径的换能器元件。当发射波束形成器被致动时，多个推动脉冲被同时发射以在对象中发起剪切波。 An ultrasonic transducer array probe (10) for shear wave imaging has a number of transducer elements which exceeds the number of transmit channels of a shear wave diagnostic imaging system. The probe includes a switch matrix or multiplexer (60) which selectively couples channels of the transmit beamformer (18) to the transducer elements of multiple shear wave apertures of the array. When the transmit beamformer is actuated, a plurality of push pulses are transmitted simultaneously to initiate shear waves in a subject.
