1. An ultrasound device, comprising:
an ultrasound transducer array comprising:
first ultrasound transducers positioned at a first azimuthal position of the ultrasound transducer array; and
second ultrasound transducers positioned at a second azimuthal position of the ultrasound transducer array;
modulation circuitry;
control circuitry configured to control the modulation circuitry to modulate and delay first ultrasound data generated by the first ultrasound transducers and second ultrasound data generated by the second ultrasound transducers such that the first ultrasound data is delayed by a first delay amount and the second ultrasound data is delayed by a second delay amount that is different from the first delay amount;
filtering circuitry configured to filter the first and second ultrasound data received from the modulation circuitry; and
summing circuitry configured to sum the first and second ultrasound data received from the filtering circuitry;
wherein the ultrasound transducer array, the control circuitry, the modulation circuitry, the filtering circuitry, and the summing circuitry are integrated onto a semiconductor chip or one or more semiconductor chips packaged together.
