## About
This is a derivative of the [TotalSegmentator](https://github.com/wasserth/TotalSegmentator) dataset, with 1228 CT images and corresponding segmentation mask of 117 structures.

- We combined multiple segmentation masks into a single `nii.gz` file under the folder `Masks`, 
and moved all CT images to the folder `Images`. 
- All images and masks are renamed according to case IDs.

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