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…
