Deep Cascade of Convolutional Neural Networks and Convolutioanl Recurrent Nerual Networks for MR Image Reconstruction
=========================================================================
Reconstruct MR images from its undersampled measurements using Deep Cascade of Convolutional Neural Networks (DC-CNN) and Convolutional Recurrent Neural Networks (CRNN-MRI). This repository contains the implementation of DC-CNN using Theano and Lasagne, and CRNN-MRI using PyTorch, along with simple demos. Note that the library requires the dev version of Lasagne and Theano, as well as pygpu backend for using CUFFT Library. PyTorch version needs to be higher than Torch 0.4. Some of the toy dataset borrowed from http://mridata.org.
- 2D Reconstruction ====================
Usage::
python main_2d.py --num_epoch 5 --batch_size 2
- Dynamic Reconstruction =========================================================================
Reconstruct dynamic MR images from its undersampled measurements using DC-CNN with Data Sharing layer. Note that the library requires CUDNN in addition to the requirement specified above.
Usage::
python main_3d.py --acceleration_factor 4
- Dynamic Reconstruction using Convolutional Recurrent Neural Networks =========================================================================
Reconstruct dynamic MR images from its undersampled measurements using Convolutional Recurrent Neural Networks. This is a pytorch implementation requiring Torch 0.4.
Usage::
python main_crnn.py --acceleration_factor 4
