Differentiable Forward and Back-Projector for Rigid Motion Estimation in X-ray Imaging
Xiao Jiang, Xin Wang, Ali Uneri +2
Objective: In this work, we propose a framework for differentiable forward and back-projector that enables scalable, accurate, and memory-efficient gradient computation for rigid m…
High-Fidelity Modeling of Detector Lag and Gantry Motion in CT Reconstruction
Steven Tilley, Alejandro Sisniega, Jeffrey H. Siewerdsen +1
Detector lag and gantry motion during x-ray exposure and integration both result in azimuthal blurring in CT reconstructions. These effects can degrade image quality both for high-…
Model-based Iterative Reconstruction for Flat-Panel Cone-Beam CT with Focal Spot Blur, Detector Blur, and Correlated Noise
Steven Tilley, Jeffrey H. Siewerdsen, J. Webster Stayman
While model-based reconstruction methods have been successfully applied to flat-panel cone-beam CT (FP-CBCT) systems, typical implementations ignore both spatial correlations in th…
Modeling shift-variant X-ray focal spot blur for high-resolution flat-panel cone-beam CT
Steven Tilley, Wojciech Zbijewski, Jeffrey H. Siewerdsen +1
Flat-panel cone-beam CT (CBCT) has been applied clinically in a number of high-resolution applications. Increasing geometric magnification can potentially improve resolution, but a…
