This repo holds the pytorch implementation of DoDNet:
DoDNet: Learning to segment multi-organ and tumors from multiple partially labeled datasets. (https://arxiv.org/pdf/2011.10217.pdf)
Python 3.7
PyTorch==1.4.0
Apex==0.1

- Clone this repo
git clone https://github.com/jianpengz/DoDNet.git
cd DoDNet
Before starting, MOTS should be re-built from the serveral medical organ and tumor segmentation datasets
| Partial-label task | Data source |
|---|---|
| Liver | data |
| Kidney | data |
| Hepatic Vessel | data |
| Pancreas | data |
| Colon | data |
| Lung | data |
| Spleen | data |
- Download and put these datasets in
dataset/0123456/. - Re-spacing the data by
python re_spacing.py, the re-spaced data will be saved in0123456_spacing_same/.
The folder structure of dataset should be like
dataset/0123456_spacing_same/
