Common mode noise suppression using channel data processing

An ultrasound processing system, comprising:

• an ultrasound interface that receives ultrasound imaging information;
• and
• processing electronics coupled to the ultrasound interface and configured to utilize the ultrasound imaging information to perform processing across a plurality of ultrasound channels by:
• selecting a channels from the plurality of ultrasound channels to be combined based on at least one of:
• a type of noise in the channels, an origin of the noise in the channels, a function of time of a transmit event in the channels, a function of depth of a spatial dimension in range in the channels, and a spatial dimension in azimuth of the channels;
• combining digital ultrasound channel data of the selected channels of the ultrasound imaging information prior to beamforming, the digital ultrasound channel data corresponding to a transmit event;
• generating weighted ultrasound channel data by applying a weighting coefficient to the combined digital ultrasound channel data;
• generating modified ultrasound channel data for each of the selected channels for adaptively reducing common mode noise of the digital ultrasound channel data from the selected channels by (i) applying a first operation to the digital ultrasound channel data using the weighted ultrasound channel data based on the common mode noise being additive noise or (ii) applying a second operation to the digital ultrasound channel data using the weighted ultrasound channel data based on the common mode noise being multiplicative noise;
• and
• providing the modified ultrasound channel data to a beamformer.
