1. An ultrasound system comprising:
an ultrasound transducer configured to transmit ultrasound pulses toward tissue and generate echo signals responsive to the ultrasound pulses;
a channel memory configured to store the echo signals;
a beamformer configured to generate beamformed radiofrequency (RF) signals responsive to the echo signals;
a graphics processing unit (GPU) configured to receive input data comprising one or more samples of the echo signals or the beamformed RF, wherein the one or more samples represent less than all of the echo signals or the beamformed RF signals, and the GPU is further configured to execute instructions to perform a machine-trained algorithm to generate a first type of ultrasound imaging data based on the input data, wherein the machine-trained algorithm is configured to select an operational mode for processing the input data from a plurality of operational modes responsive to user input or automatically set by the ultrasound system based on an imaging mode of the ultrasound system during acquisition of the echo signals; and
a processor configured to generate a second type of ultrasound imaging data based on the beamformed RF signals, wherein the processor is further configured to generate an ultrasound image based on the first type of ultrasound imaging data and the second type of ultrasound imaging data.
