Abstract

An ultrasound processing system includes an ultrasound interface and processing electronics. The ultrasound interface receives imaging information. The processing electronics are coupled to the ultrasound interface and are configured to perform processing across a plurality of ultrasound channels by combining channel data for adaptively reducing the common mode noise prior to beamforming for a transmit event. The combination of the channel data may be computing an arithmetic mean, which is then multiplied to a weighting coefficient. This value may then be removed from the individual channel data. The modified channel data is then transmitted to a beamformer, which processes the channel data for directional signal transmission and reception.
