1. A system for medical imaging, comprising:
at least one storage device including a set of instructions; and
at least one processor in communication with the at least one storage device, wherein when executing the set of instructions, the at least one processor is directed to cause the system to:
obtain a plurality of successive images of a region of interest (ROI) including at least a portion of an object's heart, wherein:
the plurality of successive images are based on imaging data acquired from the ROI by a scanner without electrocardiography (ECG) gating, and
the plurality of successive images are related to one or more cardiac cycles of the object's heart;
determine, in the plurality of successive images, two or more terminal images corresponding to the one or more cardiac cycles of the object's heart, each of the two or more terminal images correspond to the start or end of a cardiac cycle of the one or more cardiac cycles; and
determine, in the plurality of successive images, target images that correspond to at least one of the one or more cardiac cycles of the object's heart by including images between two neighboring terminal images of the two or more terminal images.
