Systems and methods for correcting motion artifacts in images are provided. The methods may include obtaining multiple preliminary images of a subject. Each of the multiple preliminary images may correspond to one of multiple phases of at least one motion cycle of the subject. The methods may also include determining an image representation of a target region of the subject in each preliminary image. The methods may also include identifying a target phase of the subject among the multiple phases of the at least one motion cycle based on the image representation of the target region in each preliminary image. The target phase and one or more neighboring phases of the target phase may correspond to a target motion status of the target region. The method may further include generating a secondary image of the subject corresponding to the target phase based on the target phase of the subject.

Systems and methods for correcting motion artifacts in images

Systems and methods for motion correction in medical imaging are provided in the present disclosure. The systems may obtain at least two image sequences relating to a subject. Each of the at least two image sequences may be reconstructed based on image data that is acquired by a medical imaging device during one of at least two time periods. The subject may undergo a physiological motion during the at least two time periods. The systems may generate, based on the at least two image sequences, at least one corrected image sequence relating to the subject by correcting, using a motion correction model, an artifact caused by the physiological motion.
