MTMR-Net

Code for Multi-Task Deep Model with Margin Ranking Loss for Lung Nodule Analysis on IEEE Transactions on Medical Imaging (TMI).

Introduction

This repository provides the PyTorch implementation for our TMI paper "Multi-Task Deep Model with Margin Ranking Loss for Lung Nodule Analysis". Our model can output a more robust benign-malignant classification result with persuasive semantic feature scores compared to other CAD techniques which can only output classification results.

Requirement

Python == 2.7.13
PyTorch == 0.3.0
tensorboardX == 0.9
numpy == 1.14.3

Installation

Download and unzip this project:

   git clone https://github.com/lihaoliu-cambridge/mtmr-net.git
   cd mtmr-net

Download resnet50.pth into ./logs/middle_result_logs/imagenet/ folder.

Dataset

Download the original LIDC-IDRI dataset into ./data/ folder

The preprocessing methods can be found in below two links:

Running

• Modify the args.yaml, add the parameters of your deep learning model under the "running_params" item. Details are shown in deep-learning-model-saving-helper project.
• Pass the running_params (a python dict which contains the running parameters) to you own model.
• The first parameter "is_training" is True for training mode, "is_training" is False for test mode.

• Finish you mode(training or test), and run it.

  cd mtmr-net
  python main.py
