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.

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.

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.

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.
