Schematic of three in-plane motion correction strategies. a) Single reference frame. All frames in a cine are registered directly to a single reference frame. b) Sequential image registration. Each pair of consecutive frames in a cine are registered sequentially toward the main reference frame. c) 2-tier sequential image registration. Subreference frames from each motion cycle are sequentially registered together toward the main reference frame. Afterwards, all other frames are sequentially registered toward the local subreference frame.
