Abstract
AbstractThis study adopted a hybrid diffusion equation with third order simplified spherical harmonics model and proposed a novel Least Square QR factorization based on the Lasso algorithm to overcome the limitation of the single proton propagation model and enable fast iteration and accurate sparse reconstruction for X‐ray Luminescence Computed Tomography (XLCT). It achieves superior reconstruction performance in terms of location accuracy, spatial resolution and materializes a balance between accuracy and efficiency.Further details can be found in the article by Hongbo Guo, Hengna Zhao, Jingjing Yu, Xiaowei He, Xuelei He, and Xiaolei Song (e202100089). image
