EDCNN: Edge enhancement-based Densely Connected Network with Compound Loss for Low-Dose CT Denoising

By Tengfei Liang, Yi Jin, Yidong Li, Tao Wang.

This repository is an official implementation of the paper EDCNN: Edge enhancement-based Densely Connected Network with Compound Loss for Low-Dose CT Denoising. arXiv IEEEXplore

Notes:

This repository provides model and loss implementation code, which can be easily integrated into the user's project.

Introduction

EDCNN is a new end-to-end Low-Dose CT Denoiser. Designed as the FCN structure, it can effectively realize the low-dose CT image denoising in the way of post-processing. With the noval edge enhancement module, densely connection and compound loss, the model has a good performance in preserving details and suppressing noise in this denoising task. (For more details, please refer to the original paper)

Denoised results

For fairness, we choose the REDCNN, WGAN and CPCE for comparison, because of their design of the single model, which is the same as our EDCNN model. All these models adopt the structure of convolutional neural networks.

    Hi, may I ask how to download the dataset. I have check the website, it's closed https://www.aapm.org/grandchallenge/lowdosect/, and use the link https://doi.org/10.7937/9npb-2637 to search. But I didn't find any dataset

    Test Datasets: The LDCT's test results are inconsistent with other papers

    In the experiment where the ratio of training set to test set is 9 to 1, the index of LDCT in your paper is 36.7594, but my personal test result is 40+, which is closer to REDCNN. I would like to ask if you adjusted the contrast of the picture before conducting the experiment, and if so, what is the value of the contrast? Thank you
