1. A method of locating moving tissue, the method comprising:

  • transmitting a first and second ultrasound pulse at a first sample volume within an object;

    receiving a first echo signal of the first ultrasound pulse from the first sample volume and a second echo signal of the second ultrasound pulse from the first sample volume;

    computing an estimate of position displacement data of the first sample volume from the first and second echo signals;

    comparing the estimate of position displacement data to a predetermined position displacement data threshold indicative of moving tissue;

    determining, based on the comparison, whether the first sample volume corresponds to moving tissue; and

    repeating, based on the determination, said transmitting, receiving, computing and determining for a second sample volume.
