An ultrasonic transducer () includes: a piezoelectric vibrator assembly (), an acoustic matching layer (), a heat sink (), and an acoustic absorption layer (). The heat sink () comprises a body (), and a head portion () and a tail portion (). The body () has a central axis extending in a direction from the head portion () to the tail portion (). A surface of the tail portion () of the heat sink () disposed away from the head portion () is a first surface (). The first surface () is an oblique surface or a tapered surface. The angle between the first surface () and the central axis is an acute angle. The acoustic absorption layer () at least covers the first surface ().

Ultrasonic transducer, ultrasonic probe, and ultrasonic detection apparatus

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.

Common mode noise suppression using channel data processing

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.
