1. An ultrasound imaging method, comprising:
acquiring, by a processor, an ultrasound volume data of an object with an ultrasonic probe;
automatically determining, by the processor using a machine learning model, position information of a target anatomical structure from the ultrasound volume data, wherein the machine learning model is a learning model obtained by training based on one or more of an Adaboost algorithm, a support vector machine (SVM), a neural network algorithm, a convolutional neural network (CNN) algorithm, a recursive neural network (RNN) algorithm, a fast region-based convolutional network (RCNN), and a single shot multibox detector (SSD);
determining, by the processor, an ultrasound image of the target anatomical structure from the ultrasound volume data according to the position information of the target anatomical structure, wherein the ultrasound image of the target anatomical structure comprises at least one of: an ultrasound image of a section corresponding to the target anatomical structure and an ultrasound image of a volume of interest (VOI) corresponding to the target anatomical structure; and
displaying, by the processor, the ultrasound image of the target anatomical structure on a display device, wherein in response to the ultrasound image of the target anatomical structure comprising the ultrasound image of the VOI corresponding to the target anatomical structure, determining, by the processor, the ultrasound image of the target anatomical structure from the ultrasound volume data according to the position information of the target anatomical structure comprises:
determining position information of a target section according to the position information of the target anatomical structure; and
setting a size and position information of the VOI corresponding to the target anatomical structure in the ultrasound volume data according to the position information of the target section, comprising:
automatically setting a proportion of a volume surrounded by the VOI corresponding to the target anatomical structure to a total volume of the target anatomical structure to be greater than a preset volume threshold, wherein the size of the VOI corresponding to the target anatomical structure comprises length, width, and height, and the VOI corresponding to the target anatomical structure contains all or part of the target anatomical structure; and
rendering the VOI corresponding to the target anatomical structure to obtain a stereoscopic image of the target anatomical structure as the ultrasound image of the VOI corresponding to the target anatomical structure.
