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.

Abstract: A computing system includes a memory configured to store instructions, and one or more processors configured to execute the instructions to receive data relating to an image or a user, determine a feature from the data, identify a user preference from a user profile, obtain a model, and segment the image based on the feature, the user preference, and the model. The model is generated by determining a historical feature from historical data as an input, determining a desired output, obtaining a preliminary model based on the input and the desired output, determining an actual output of the preliminary model, determining error criteria between the actual output and the desired output, and generating the model by updating the preliminary model based on the error criteria.

Abstract: An ultrasound system includes an ultrasound transducer, a processing circuit, and an output device. The ultrasound transducer detects ultrasound information and outputs the ultrasound information as ultrasound data samples. The processing circuit receives ultrasound data samples from the ultrasound transducer, calculates a plurality of first spectra for a first subset of the received ultrasound data samples, generates a threshold based on the plurality of first spectra, categorizes first spectra greater than the threshold as signal data, otherwise as noise data, processes the signal data using a first signal processing parameter and the noise data using a second signal processing parameter different from the first signal processing parameter, and combines the processed signal data and noise data into an ultrasound output. The output device is configured to output the ultrasound output as at least one of an ultrasound image or ultrasound audio.
