ADN: Artifact Disentanglement Network for Unsupervised Metal Artifact Reduction

liaohaofu/adn 3 Aug 2019

Current deep neural network based approaches to computed tomography (CT) metal artifact reduction (MAR) are supervised methods that rely on synthesized metal artifacts for training.

Fast Enhanced CT Metal Artifact Reduction using Data Domain Deep Learning

mughanibu/DeepMAR 9 Apr 2019

The subsequent complete projection data is then used with FBP to reconstruct image intended to be free of artifacts.

Artifact Disentanglement Network for Unsupervised Metal Artifact Reduction

liaohaofu/adn 5 Jun 2019

Extensive experiments show that our method significantly outperforms the existing unsupervised models for image-to-image translation problems, and achieves comparable performance to existing supervised models on a synthesized dataset.

DAN-Net: Dual-Domain Adaptive-Scaling Non-local Network for CT Metal Artifact Reduction

zjk1988/DAN-Net 16 Feb 2021

With the rapid development of deep learning in the field of medical imaging, several network models have been proposed for metal artifact reduction (MAR) in CT.

InDuDoNet: An Interpretable Dual Domain Network for CT Metal Artifact Reduction

hongwang01/indudonet 11 Sep 2021

For the task of metal artifact reduction (MAR), although deep learning (DL)-based methods have achieved promising performances, most of them suffer from two problems: 1) the CT imaging geometry constraint is not fully embedded into the network during training, leaving room for further performance improvement; 2) the model interpretability is lack of sufficient consideration.

InDuDoNet+: A Deep Unfolding Dual Domain Network for Metal Artifact Reduction in CT Images

hongwang01/indudonet_plus 23 Dec 2021

To alleviate these issues, in the paper, we construct a novel deep unfolding dual domain network, termed InDuDoNet+, into which CT imaging process is finely embedded.

Adaptive Convolutional Dictionary Network for CT Metal Artifact Reduction

hongwang01/ACDNet 16 May 2022

By unfolding every iterative substep of the proposed algorithm into a network module, we explicitly embed the prior structure into a deep network, \emph{i. e.,} a clear interpretability for the MAR task.

Quad-Net: Quad-domain Network for CT Metal Artifact Reduction

longzilicart/quad-net 24 Jul 2022

Here we extend the state-of-the-art dual-domain deep network approach into a quad-domain counterpart so that all the features in the sinogram, image, and their corresponding Fourier domains are synergized to eliminate metal artifacts optimally without compromising structural subtleties.

Orientation-Shared Convolution Representation for CT Metal Artifact Learning

hongwang01/oscnet 26 Dec 2022

During X-ray computed tomography (CT) scanning, metallic implants carrying with patients often lead to adverse artifacts in the captured CT images and then impair the clinical treatment.

MEPNet: A Model-Driven Equivariant Proximal Network for Joint Sparse-View Reconstruction and Metal Artifact Reduction in CT Images

hongwang01/mepnet 25 Jun 2023

Sparse-view computed tomography (CT) has been adopted as an important technique for speeding up data acquisition and decreasing radiation dose.
