1. An apparatus for reducing reverberation artifacts in an ultrasound image, comprising:
a processor circuit in communication with an ultrasound transducer, wherein the processor circuit is configured to:
control the ultrasound transducer to obtain a plurality of ultrasound images using a respective plurality of pulse repetition intervals;
calculate an amount of reverberation artifacts in each of the plurality of ultrasound images;
select a pulse repetition interval based on the amounts of reverberation artifacts in each of the plurality of ultrasound images;
in response to selecting the pulse repetition interval, control the ultrasound transducer to obtain a reduced- reverberation ultrasound image at the selected pulse repetition interval; and
output the reduced-reverberation ultrasound image to a display in communication with the processor circuit.
