Abstract: Provided in the present invention are a magnetic resonance imaging system and method, and a computer-readable storage medium. The method comprises: performing a medical scan of a subject and acquiring a first medical image having a first noise interference artifact, and performing an additional scan of the subject to acquire a second medical image, wherein the second medical image has a second noise interference artifact, and the location mapping of the second noise interference artifact in the first medical image is symmetrical to the location of the first noise interference artifact relative to a pixel center of the first medical image; and performing synthesis-related processing on the first medical image and the second medical image to acquire a post-processed image with reduced noise interference artifacts.

Abstract: Provided in the present application are a target area determination method and a medical imaging system, specifically a target area determination method and device, a medical imaging system, and a non-transitory computer-readable storage medium. The target area determination method includes: pre-processing an original image to acquire a pre-processed medical image, acquiring a target point in the medical image, and acquiring a plurality of sectional images of the medical image according to the target point, and acquiring, on the basis of a first model, a target area corresponding to the target point in the plurality of sectional images.

Abstract: Various methods and systems are provided for automatically registering and stitching images. In one example, a method includes entering a first image of a subject and a second image of the subject to a model trained to output a transformation matrix based on the first image and the second image, where the model is trained with a plurality of training data sets, each training data set including a pair of images, a mask indicating a region of interest (ROI), and associated ground truth, automatically stitching together the first image and the second image based on the transformation matrix to form a stitched image, and outputting the stitched image for display on a display device and/or storing the stitched image in memory.
