HIT: 398 Paired Volumetric MRI Scans and SMPL Body Surface Meshes

The HIT dataset contains 398 paired observations of internal body tissues and external surface shapes, released by varora in 2024. It features volumetric segmented MRI scans identifying bones, lean, and adipose tissue alongside corresponding SMPL meshes for 157 male and 241 female subjects.

Use Cases

• Predicting internal bone and adipose tissue distribution from SMPL surface mesh parameters
• Training 3D segmentation models for volumetric MRI tissue classification
• Generating personalized anatomical digital twins for biomechanical simulation

Strengths

• 398 paired internal/external body observations
• Segmented labels for bones, lean, and adipose tissue
• Standardized SMPL mesh format for surface shape

Limitations

• Small sample size of 398 subjects for deep learning
• Gender imbalance with 241 female and 157 male subjects
• Unknown demographic or geographic diversity
