Title: 3D MRI Image Pretraining via Controllable 2D Slice Navigation Task
Abstract:
arXiv:2605.06487v1 Announce Type: cross Abstract: Self-supervised pretraining has become the mainstream approach for learning MRI representations from unlabeled scans. However, most existing objectives still treat each scan primarily as static aggregations of slices, patches or volumes. We ask whether there exists an intrinsic form of self-supervision signal that is different from reconstructing the masked patches, through transforming the 3D volumes into controllable 2D rendered sequences: by r
