1. A system, comprising:
an ultrasound transducer; and
a computing device configured to directly receive ultrasound data sensed by the ultrasound transducer from a person, the received ultrasound data comprising a sequence of ultrasound images, the computing device comprising:
a processor configured to perform a method, the method comprising:
receiving a first ultrasound image from the ultrasound transducer;
receiving user input selecting an anatomical structure appearing in the first ultrasound image;
performing localization based on segmentation or key point detection of the first ultrasound image performed by:
applying a convolutional neural network to aliasing patterns in the first ultrasound image that are associated with blood flow through the person to obtain a probability map signifying a spatial location of the aliasing patterns in the first ultrasound image and the direction of the blood flow; and
determining a location of the selected anatomical structure in the first ultrasound image based on the probability map;
automatically performing a first placement of measurement location controls relative to the determined location of the selected anatomical structure;
causing the ultrasound transducer to implement one or more first Doppler ultrasound modes using the determined first measurement location control placement;
receiving one or more second ultrasound images from the ultrasound transducer using the one or more first Doppler ultrasound modes;
determining a flow location and flow direction based on the one or more second ultrasound images;
automatically performing a second placement of measurement location controls relative to the determined flow location;
causing the ultrasound transducer to implement one or more second Doppler ultrasound modes using the second measurement location control placement; and
receiving results in response to causing the ultrasound transducer to implement the one or more second Doppler ultrasound modes.
