A method for ultrasound data processing includes transmitting an ultrasound excitation signal from each element of a transducer array and receiving a response signal from each element of a transducer array. Each response signal corresponds to a respective channel. Each response signal is sampled at one or more time points in the response signal to create a plurality of samples, each sample corresponding to a channel and a time point. The samples are divided into at least two groups. Response signals from the first group are beamformed and response signals from the second group are beamformed separately. The process is repeated over multiple data frames. The beamformed signals of each group are correlated over the multiple data frames and beamformed signals having a lower degree of correlation or negative correlation are selectively attenuated. An image output is generated from the correlation output.
