OpenMind2D: 2D Brain MRI Slices

OpenMind2D is a 2D medical imaging dataset derived from the OpenMind dataset. It contains 335,754 2D slices extracted from 3D brain MRI volumes in three anatomical orientations (axial, sagittal, coronal).

Dataset Statistics

Total Images: 335,754
Resolution: 256×256 pixels
Format: JPEG
Size: ~11.7 GB
Splits: Train (70%), Validation (20%), Test (10%)
Orientations: Axial, sagittal, coronal
Modalities: T1w, T2w, FLAIR, DWI, and 19+ additional MRI types

Source

This dataset is derived from the OpenMind dataset (Dufumier et al., 2024), which contains 114,000 3D brain MRI volumes from 800 OpenNeuro datasets.

Processing

Slice extraction from three anatomical orientations
Isotropic resampling to 1mm³ spacing
Intensity normalization (1st-99th percentile clipping)
Resize to 256×256 pixels
JPEG compression with metadata preservation
