Foveated-Imaging Geometry CT Architecture and Seeded Diffusion Model Enabling Global Super-Resolution Reconstruction
Wenxin Mo, Yingxian Xia, Yongle Yan +3
For X-ray computed tomography (CT), a smaller detector pixel size generally leads to higher scanner spatial resolution, but inevitably increases system cost as well as data overhea…
Penumbra-Effect Induced Spectral Mixing in X-ray Computed Tomography: A Multi-Ray Spectrum Estimation Model and Subsampled Weighting Algorithm
Yifan Deng, Hao Zhou, Hewei Gao
Purpose: With the development of spectral CT, several novel spectral filters have been introduced to modulate the spectra, such as split filters and spectral modulators. However, d…
Fast KV-Switching and Dual-Layer Flat-Panel Detector Enabled Cone-Beam CT Joint Spectral Imaging
Hao Zhou, Li Zhang, Zhilei Wang +1
Purpose: Fast kV-switching (FKS) and dual-layer flat-panel detector (DL-FPD) technologies have been actively studied as promising dual-energy solutions for FPD-based cone-beam comp…
Multi-Energy Blended CBCT Spectral Imaging Using a Spectral Modulator with Flying Focal Spot (SMFFS)
Yifan Deng, Hao Zhou, Zhilei Wang +2
Conventional cone-beam CT (CBCT) can be easily compromised by scatter and beam hardening artifacts, and the entanglement of scatter and spectral effects introduces additional compl…
An Analysis of Scatter Characteristics in X-ray CT Spectral Correction
Tao Zhang, Zhiqiang Chen, Hao Zhou +3
X-ray scatter remains a major physics challenge in volumetric computed tomography (CT), whose physical and statistical behaviors have been commonly leveraged in order to eliminate…
