# Automatic lung tumor segmentation in CT

[![Build Actions Status](https://github.com/VemundFredriksen/LungTumorMask/workflows/Build/badge.svg)](https://github.com/VemundFredriksen/LungTumorMask/actions)

This is the official repository for the paper [_"Teacher-Student Architecture for Mixed Supervised Lung Tumor Segmentation"_](https://arxiv.org/abs/2112.11541), **accepted for publication** in PLOS ONE.

A pretrained model is made available in a command line tool and can be used as you please. However, the current model is not intended for clinical use. The model is the result of a proof-of-concept study. An improved model will be made available in the future, when more training data is made available.

## Dependencies
In addition to the python packages specified in requirements.txt, [PyTorch](https://pytorch.org/get-started/locally/) and [lungmask](https://github.com/JoHof/lungmask) must be installed.

## Installation
```
pip install git+https://github.com/VemundFredriksen/LungTumorMask
```

## Usage
After install, the software can be used as a command line tool. Simply specify the input and output filenames to run:
```
# Format
lungtumormask input_file output_file

# Example
lungtumormask patient_01.nii.gz mask_01.nii.gz
```
