PND-Net: Physics based Non-local Dual-domain Network for Metal Artifact Reduction
Jinqiu Xia, Yiwen Zhou, Hailong Wang +7
Metal artifacts caused by the presence of metallic implants tremendously degrade the reconstructed computed tomography (CT) image quality, affecting clinical diagnosis or reducing…
A method for real-time volumetric imaging in radiotherapy using single x-ray projection
Yuan Xu, Hao Yan, Luo Ouyang +5
In this paper, we present a new method to generate an instantaneous volumetric image using a single x-ray projection. To fully extract motion information hidden in projection image…
Reconstruction from Radon projections and orthogonal expansion on a ball
Yuan Xu
The relation between Radon transform and orthogonal expansions of a function on the unit ball in $\RR^d$ is exploited. A compact formula for the partial sums of the expansion is gi…
Fast OPED algorithm for reconstruction of images from Radon data
Yuan Xu, Oleg Tischenko
A fast implementation of the OPED algorithm, a reconstruction algorithm for Radon data introduced recently, is proposed and tested. The new implementation uses FFT for discrete sin…
Approximation and Reconstruction from Attenuated Radon Projections
Yuan Xu, Oleg Tischenko, Christoph Hoeschen
Attenuated Radon projections with respect to the weight function are shown to be closely related to the orthogonal expansion in two variables with…
A new approach to the reconstruction of images from Radon projections
Yuan Xu
A new approach is proposed for reconstruction of images from Radon projections. Based on Fourier expansions in orthogonal polynomials of two and three variables, instead of Fourier…
