Implementation of Low-Dose CT with a Residual Encoder-Decoder Convolutional Neural Network (RED-CNN)
There is several things different from the original paper.
- The input image patch(64x64 size) is extracted randomly from the 512x512 size image. --> Original : Extract patches at regular intervals from the entire image.
- use Adam optimizer

- run
python prep.py
to convert 'dicom file' to 'numpy array' - run
python main.py --load_mode=0
to training. If the available memory(RAM) is more than 10GB, it is faster to run--load_mode=1
. - run
python main.py --mode='test' --test_iters=100000
to test.
