Abstract: Highlights•Temporal Interpolation for reducing navigator acquisitions in navigated 4D MRI.•We propose interpolation via motion field prediction as an intermediate step.•Leads to sharp interpolated images, with preserved image content.•Novel cycle-consistency loss further improves interpolation results.•Unsupervised estimation of motion field can greatly reduce 4D reconstruction time.
