Respiratory motion characterization and uncertainty estimation is important in radiotherapy treatment planning, and is hindered by the imaging capability of 4DCT or time-resolved single/multi-slice MRI (2D+t). In this study, characterization of the positional and orientation uncertainty of abdominal organ respiratory motion, extracted from the time-resolved volumetric 3D+t MRI, was done using bootstrapping and tensor analysis.
