# DeepLesion Benchmark Subset (Balanced 2K)

This dataset is a curated subset of the [DeepLesion dataset](https://nihcc.app.box.com/v/DeepLesion), prepared for demonstration and benchmarking purposes. It consists of 2,000 CT lesion samples, balanced across 8 coarse lesion types, and filtered to include lesions with a short diameter > 10mm.

## Dataset Details

- **Source**: [DeepLesion](https://nihcc.app.box.com/v/DeepLesion)
- **Institution**: National Institutes of Health (NIH) Clinical Center
- **Subset size**: 2,000 images
- **Lesion types**: lung, abdomen, mediastinum, liver, pelvis, soft tissue, kidney, bone
- **Selection criteria**:
  - Short diameter > 10mm
  - Balanced sampling across all types
- **Windowing**: All slices were windowed using DICOM parameters and converted to 8-bit PNG format

## Intended Uses

- Embedding demos
- Lesion similarity and retrieval
- Benchmarking medical image models
- Few-shot learning on lesion types

## Limitations

- This is a small subset of the full DeepLesion dataset
- Not suitable for training full detection models
- Labels are coarse and may contain inconsistencies
