Geometry-Consistent Discretization of Local Correlation Equations for the Radon Transform in Clinical CT
Xuanqing Mou, Jiayu Duan, Yang Mou
In this work, we extend the local correlation equation (LCE) framework of the 2D Radon transform to clinical computed tomography (CT) geometry and propose a set of geometry-consist…

A CT Geometry With Multiple Centers Of Rotation For Solving Sparse View Problem
Jiayu Duan, Yang Li, Jianmei Cai +1
With the emergence of CNT (Carbon nanotube), static and instant CT scanning becomes possible. By transforming the traditionally rotated thermal source into a static ring array sour…

Exploring the redundancy of Radon transform using a set of partial derivative equations: Could we precisely reconstruct the image from a sparse-view projection without any image prior?
Xuanqin Mou, Jiayu Duan
In this study, we proposed a universal n-th order partial differential equation (PDE) of 2-D Radon transform to disclose the relationship of Radon transform over a neighborhood of…
