# LUNA25 TS Segmentations

The [LUNA25 challenge](https://luna25.grand-challenge.org/) serves as a benchmark for evaluating lung nodule detection in low-dose CT scans. This repository includes segmentations generated using [TotalSegmentator](https://github.com/wasserth/TotalSegmentator) for the `total`, `lung_vessels`, and `lung_nodules` tasks. Note: Segmentation volumes have not been independently verified and are supplied "as is".

## Steps to recreate

1. Use `scripts/convert_nifti.py` and `scripts/convert_nifti.sh` to convert LUNA25 `.mha` files to `.nii.gz`.
2. Install [TotalSegmentator](https://github.com/wasserth/TotalSegmentator).
3. Run TS segmentation scripts (written for parallel execution):
	- `scripts/ts_total.sh`
	- `scripts/ts_lung_vessels.sh`
	- `scripts/ts_lung_nodules.sh`
4. Run `scripts/get_metadata.py` to get metadata for detected lung nodules.
