Abstract

Detection of tissue response is provided with a high pulse repetition frequency. A sequence of separable signals is transmitted in one event. For example, pulses at different frequencies are transmitted as separate waveforms, but in rapid succession. As another example, coded transmit pulses are used. After transmission of the pulses, signals are received. Based on the different frequencies or coding, tissue response is measured at different times based on the receive event. Instead of one measure, a plurality of measures are provided for a given transmit and receive event pair, increasing the effective pulse repetition frequency for shear or elasticity imaging.
