SAML & A Multi-site Dataset for Prostate MRI Segmentation

by Quande Liu, Qi Dou, Pheng-Ann Heng.

Introduction

• The Tensorflow implementation for our MICCAI 2020 paper 'Shape-aware Meta-learning for Generalizing Prostate MRI Segmentation to Unseen Domains'.

• A well-organized multi-site dataset (from six data sources) for prostate MRI segmentation, that can support research in various problem settings with need of multi-site data, such as Domain Generalization, Multi-site Learning and Life-long Learning, etc. For more details and downloading link of the dataset, please Find Here.

Setup & Usage for the Code

1. Check dependencies:

   python==2.7.17
   numpy==1.16.6
   scipy==1.2.1
   tensorflow-gpu==1.12.0
   tensorboard==1.12.2
   SimpleITK==1.2.0

2. To train the model, you need to specify the training configurations (can simply use the default setting) in main.py, then run:

   python main.py --phase=train

3. To evaluate the model, run:

   python main.py --phase=test --restore_model='/path/to/test_model.cpkt'

   You will see the output results in the folder ./output/.
