Claim 16:
17. A method of ultrasound imaging comprising:
receiving an indication of a recurring patient by at least one processor of an ultrasound imaging system;
responsive to the indication of the recurring patient, automatically retrieving a plurality of previous ultrasound images associated with the recurring patient and previous imaging parameter settings associated with the plurality of previous ultrasound images from a source of previously-acquired ultrasound image data;
generating a current ultrasound image of biological tissue of the recurring patient using current imaging parameter settings;
providing the current ultrasound image and the plurality of previous ultrasound images to a neural network to identify a matching previous image of the recurring patient, wherein the neural network identifies the matching previous image by:
receiving, by the at least one neural network, the current ultrasound imaging in parallel with the current imaging parameter settings provided as a settings vector comprising values of ultrasound imaging parameter settings;
converting the current ultrasound image, together with the settings vector to a first feature vector,
converting a previous ultrasound image of the plurality of previous ultrasound images, together with respective previous imaging parameter settings of the previous imaging parameter settings, to a second feature vector,
computing a distance metric between the first feature vector and the second feature vector, and
identifying the previous ultrasound image as the matching previous image based on the distance metric; and

causing a user interface to concurrently display the current ultrasound image and successive ones of the plurality of previous ultrasound images as successive image pairs, wherein each of the successive ones of the plurality of previous ultrasound images is displayed while determining whether the current ultrasound image and each successive one of the plurality of previous ultrasound images correspond to a same imaging plane, wherein determining whether the current ultrasound image and each successive one of the plurality of previous ultrasound images correspond to the same imaging plane includes identifying the matching previous image of the recurring patient, and wherein the user interface dynamically updates to cycle through the successive image pairs;
responsive to an identification of the matching previous image, automatically adjusting one or more imaging parameters of the ultrasound imaging system to correspond to particular imaging parameter settings of the previous imaging parameter settings associated with the matching previous image and acquiring a new ultrasound image with the adjusted imaging parameters.
