Knee abnormalities and pain are sometimes elucidated during motion, therefore the ability to obtain 4D images of the moving knee could add diagnostic value to the conventional static MRI scans. In this work we present a method to obtain 4D imaging of the human knee during motion, without the use of an external gating system.
