MR RATE: A Vision Language Foundation Model and Dataset for Magnetic Resonance Imaging This is the MR RATE atlas repository, part of the MR RATE dataset release. It contains atlas registered MRI volumes in which all imaging sequences within each study have been spatially normalized to a standard atlas space. For full dataset details, native space MRI volumes, radiology reports, metadata, and data splits, please refer to the MR RATE repository. To explore, download, and work with the dataset see Dataset Organization & Getting Started . [2026 04 19] Some studies initially missing due to processing job failures have been uploaded. See the backfill guide for details. Atlas Registered MRI Volumes Within each study in native space, a T1 weighted MRI volume is selected as the center modality and is rigidly registered to the MNI152 (ICBM 2009c Nonlinear Symmetric) atlas using ANTs. All other MRI volumes acquired in the same study referred to as moving modalities , and the brain mask and defacing mask of center modality are then transformed to atlas space by composing the native to center transforms (from MR RATE coreg) and center to atlas registration transforms, bringing all sequences of…
