Reconstruct MR images from its undersampled measurements using Deep Cascade of Convolutional Neural Networks (DC-CNN). This repository contains the implementation of DC-CNN using Theano and Lasagne and the simple demo. Note that the library requires the dev version of Lasagne and Theano, as well as pygpu backend for using CUFFT Library. Some of the toy dataset borrowed from <http://mridata.org>.
Usage:
python main_2d.py --num_epoch 5 --batch_size 2
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
