Patient-specific respiratory liver motion analysis for individual motion-resolved reconstruction

Respiratory motion is a major source of artefacts in abdominal MRI and varies considerably across subjects. Motion-resolved strategies utilize the periodic nature of respiratory motion, but do not always consider absolute patient-specific motion information. The purpose of the present work is to develop a framework incorporating the patient-specific absolute body motion into a motion-resolved reconstruction (XD-GRASP), while adapting different motion binning strategies. To explore the potential of respiratory motion knowledge for MR reconstruction, individual absolute body motion, i.e. of the liver, is identified.
