Abstract:
A method of scanning tissue in a body using transit ultrasound beams, the method comprising the step of generating a plurality of transmit ultrasound beams in a plurality of directions, wherein at least two of the plurality of transmit ultrasound beams are generated at a different associated frequency, wherein a time interval from a first start time of one of the plurality of transmit ultrasound beams to a second start time of another of the plurality of transmit ultrasound beams is less than a total time for one of the plurality of transmit ultrasound beams to propagate from an ultrasound transducer array to a maximum scan range in the region and a corresponding reflected pressure wave to propagate from the maximum scan range to the ultrasound transducer array.
