3D MR Image Sequences of the Heart

A magnetic resonance (MR) imaging system configured to generate MR images of a heart of a patient, the system comprising:

• one or more processors;
• and
• a memory storing instructions that, when executed by the one or more processors, cause the MR imaging system to:
• select first 3D MR datasets acquired at a first breath hold of the patient over a plurality of cardiac phases;
• select second 3D MR datasets acquired at a second breath hold of the patient over several cardiac phases;
• generate a first combined MR dataset based on at least some of the selected first 3D MR datasets at the first breath hold;
• generate a second combined MR dataset based on at least some of the selected second 3D MR datasets at the second breath hold;
• determine motion information for the heart between the first and second breath hold based on the first and second combined MR dataset;
• and
• reconstruct, for each of the plurality of cardiac phases, MR images of the heart based on the first 3D MR datasets, the motion information, and the second 3D MR dataset.
