## About
This is a subset of the [SegRap23 dataset](https://segrap2023.grand-challenge.org/dataset/).
- 120 images (for both contrast-CT and CT) and segmentation masks (for both tasks 1 and 2 in [SegRap23 challenge](https://segrap2023.grand-challenge.org))
- No change to any image or segmentation mask
- Files are renamed according to case IDs

This dataset is released under the `CC BY-NC 4.0` license.
