ResDynUNet++: A nested U-Net with residual dynamic convolution blocks for dual-spectral CT
Ze Yuan, Wenbin Li, Shusen Zhao
We propose a hybrid reconstruction framework for dual-spectral CT (DSCT) that integrates iterative methods with deep learning models. The reconstruction process consists of two com…

A multilayer level-set method for eikonal-based traveltime tomography
Wenbin Li, Ken K. T. Hung, Shingyu Leung
We present a novel multilayer level-set method (MLSM) for eikonal-based first-arrival traveltime tomography. Unlike classical level-set approaches that rely solely on the zero-leve…
