1. A method for guiding an ultrasound imaging procedure, comprising:
receiving one or more ultrasound images of a subject acquired through an ultrasound imaging system;
evaluating said one or more ultrasound images using a trained machine learning model comprising a representation of a three-dimensional structure of a target volume of the subject to determine a current position of a probe of the ultrasound imaging system and/or a clinical image quality;
identifying an optimal probe position for imaging for at least one sub-view of the target volume of the subject;
generating one or more probe movements for reducing a difference between the current probe position and the identified optimal probe position; and
providing guidance instructions to a user of the ultrasound imaging system to make a plurality of generated movements comprising alternate movements corresponding to a single sub-view,
wherein the guidance instructions further comprise an indication of a computed confidence or probability of the alternate movements corresponding to the single sub-view.
