1. A method for an ultrasound system including a plurality of ultrasound transducers each coupled to a respective receive channel, comprising:
time-delaying a set of ultrasound receive channel signals to form a plurality of time-delayed sets of ultrasound receive channel signals, each time-delayed set of ultrasound receive channel signals time-delayed based on a different beamforming sound speed;
calculating a beamforming quality metric for each receive channel and for each time-delayed set of ultrasound receive channel signals; and
generating an ultrasound image from ultrasound receive channel signals selected from the plurality of time-delayed sets of ultrasound receive channel signals based on each beamforming quality metric.
