Zhu, Wentao, Chaochun Liu, Wei Fan, and Xiaohui Xie. "DeepLung: Deep 3D Dual Path Nets for Automated Pulmonary Nodule Detection and Classification." IEEE WACV, 2018.

Deepem: Deep 3d convnets with em for weakly supervised pulmonary nodule detection, MICCAI, 2018.

Dependecies: Ubuntu 14.04, python 2.7, CUDA 8.0, cudnn 5.1, h5py (2.6.0), SimpleITK (0.10.0), numpy (1.11.3), nvidia-ml-py (7.352.0), matplotlib (2.0.0), scikit-image (0.12.3), scipy (0.18.1), pyparsing (2.1.4), pytorch (0.1.10+ac9245a) (anaconda is recommended)

Download LUNA16 dataset from https://luna16.grand-challenge.org/data/

Download LIDC-IDRI dataset from https://wiki.cancerimagingarchive.net/display/Public/LIDC-IDRI

For preprocessing, run ./DeepLung/prepare.py. The parameters for prepare.py is in configtraining.py.
*
datapath is the unzip raw data path for LUNA16.
*
preprocessresultpath is the save path for the preprocessing.
*annospath is the path for annotations.
*_segment is the path for LUNA16 segmentation, which can be downloaded from LUNA16 website.

Use run_training.sh to train the detector.
You can use the ResNet or dual path net model by revising --model attribute.
After training and test are done, use the ./evaluationScript/frocwrtdetpepchluna16.py to validate the epoch used for test.
After that, collect all the 10 folds' prediction, use ./evaluationScript/noduleCADEvaluationLUNA16.py to get the FROC for all 10 folds.
You can directly run noduleCADEvaluationLUNA16.py, and get the performance in the paper.

The trained model is in ./detector/dpnmodel/ or ./detector/resmodel/ The performances on each fold are (these results are in the supplement)

For nodule classification, first clean the data from LIDC-IDRI.
Use the ./data/extclsshpinfo.py to extract nodule labels.
humanperformance.py is used to get the performance of doctors.

dimcls.py is used to get the classification based on diameter.
nodclsgbt.py is used to get the performance based on GBM, nodule diameter and nodule pixel.
pthumanperformance.py is used for patient-level diagnosis performance.
kappatest.py is used for kappa value calculation in the paper.

For classification using DPN, use the code in main_nodcls.py.
You may revise the code a little bit for different test settings.

For system's classification, that is classification based on detection.
First, use the detection's test script in the run_training.sh to get the detected nodules for training CTs.
Use the det2cls.py to train the model. And use the testdet2cls.py to test the trained model.
You may revise the code a little bit for different test settings.

Doctor's annotation for each nodule in LIDC-IDRI is in ./nodcls/annotationdetclssgm_doctor.csv

Feel free to ask any questions. Wentao Zhu, [email protected]

LIDC-IDRI nodule size report downloaded from http://www.via.cornell.edu/lidc/list3.2.csv is in /nodcls/data/list3.2.csv
