CT Lung Segmentation

This repository contains the codes for lung and airway segmentation from CT scans, used in "Discriminative Localization in CNNs for Weakly-Supervised Segmentation of Pulmonary Nodules", MICCAI'17.

Files

demo_ct_lung_segment.ipynb: demo code to walk through the steps implementated in main.py.
main.py: main code of the segmentation.
segment_lung.py: coarse segmentation of lung & airway.
segment_airway.py: extraction of airway.
utils.py: utility functions.
data: input sample.
result: output sample.

Note: the sample image is down-sampled from a CT scans in the LIDC-IDRI dataset.
