Parallel Diffusion Model-based Sparse-view Cone-beam Breast CT

no code implementations22 Mar 2023 Wenjun Xia, Hsin Wu Tseng, Chuang Niu, Wenxiang Cong, Xiaohua Zhang, Shaohua Liu, Ruola Ning, Srinivasan Vedantham, Ge Wang

Specifically, in this study we transform the cutting-edge Denoising Diffusion Probabilistic Model (DDPM) into a parallel framework for sub-volume-based sparse-view breast CT image reconstruction in projection and image domains.

Deep Efficient End-to-end Reconstruction (DEER) Network for Few-view Breast CT Image Reconstruction

1 code implementation9 Dec 2019 Huidong Xie, Hongming Shan, Wenxiang Cong, Chi Liu, Xiaohua Zhang, Shaohua Liu, Ruola Ning, Ge Wang

Breast CT provides image volumes with isotropic resolution in high contrast, enabling detection of small calcification (down to a few hundred microns in size) and subtle density differences.

Deep-learning-based Breast CT for Radiation Dose Reduction

no code implementations25 Sep 2019 Wenxiang Cong, Hongming Shan, Xiaohua Zhang, Shaohua Liu, Ruola Ning, Ge Wang

In this study, we propose a deep-learning-based method to establish a residual neural network model for the image reconstruction, which is applied for few-view breast CT to produce high quality breast CT images.
