# The Cancer Genome Atlas Ovarian Cancer (NSCLC-Radiomics)

The models featured in this repository uses images from the publicly available [NSCLC-Radiomics](https://wiki.cancerimagingarchive.net/display/Public/NSCLC-Radiomics) Dataset. 

Download the data from TCIA with **Classic Directory Name** download option.

## Converting Format

Convert DICOM images and segmentation to NIFTI format using SimpleITK, [pydicom](https://pydicom.github.io/) and [pydicom-seg](https://razorx89.github.io/pydicom-seg/guides/read.html). Run:

```shell
user@machine:~/NSCLC-Radiomics-NIFTI$ python convert.py
```

## Segmentations

Images will have one of the following segmentation files:

```
─ seg-Esophagus.nii.gz    # 1
─ seg-GTV-1.nii.gz        # 2
─ seg-Heart.nii.gz        # 3
─ seg-Lung-Left.nii.gz    # 4
─ seg-Lung-Right.nii.gz   # 5
─ seg-Spinal-Cord.nii.gz  # 6
```

To combine segmentations into single nifti file, run `combine_segmentations.py`.

## Requirements

```
pandas==1.5.0
pydicom==2.3.1
pydicom-seg==0.4.1
SimpleITK==2.2.0
tqdm==4.64.1
```
