Motion analysis in 4D MRI of the small intestine using neural networks

Movement of the small intestine is rather difficult to measure. It can be done by manometry ( pressure measurements using sensors on a catheter), but this procedure is very invasive. A non-invasive modality that can offer an alternative is 4D MRI . This involves taking multiple 3D MRI images in quick succession so that they can be played back as a video. While 4D MRI scans for the small
