MedicalNet
This repository contains a Pytorch implementation of Med3D: Transfer Learning for 3D Medical Image Analysis. Many studies have shown that the performance on deep learning is significantly affected by volume of training data. The MedicalNet project aggregated the dataset with diverse modalities, target organs, and pathologies to to build relatively large datasets. Based on this dataset, a series of 3D-ResNet pre-trained models and corresponding transfer-learning training code are provided.

Update(2019/07/30)
We uploaded 4 pre-trained models based on more datasets (23 datasets).
Model name : parameters settings
resnet_10_23dataset.pth: --model resnet --model_depth 10 --resnet_shortcut B
resnet_18_23dataset.pth: --model resnet --model_depth 18 --resnet_shortcut A
resnet_34_23dataset.pth: --model resnet --model_depth 34 --resnet_shortcut A
resnet_50_23dataset.pth: --model resnet --model_depth 50 --resnet_shortcut B
We transferred the above pre-trained models to the multi-class segmentation task (left lung, right lung and background) on Visceral dataset. The results are as follows:
Contents

- Performance
Visualization of the segmentation results of our approach vs. the comparison ones after the same training epochs.
It has demonstrated that the efficiency for training convergence and accuracy based on our MedicalNet pre-trained models.
Results of transfer MedicalNet pre-trained models to lung segmentation (LungSeg) and pulmonary nodule classification (NoduleCls) with Dice and accuracy evaluation metrics, respectively.
