End-to-End Differentiable Photon Counting CT
Sen Wang, Yirong Yang, Jooho Lee +2
Quantitative imaging is an important feature of spectral X-ray and CT systems, especially photon-counting CT (PCCT) imaging systems, which is achieved through material decompositio…
Scout-Dose-TCM: Direct and Prospective Scout-Based Estimation of Personalized Organ Doses from Tube Current Modulated CT Exams
Maria Jose Medrano, Sen Wang, Liyan Sun +5
This study proposes Scout-Dose-TCM for direct, prospective estimation of organ-level doses under tube current modulation (TCM) and compares its performance to two established metho…
A coronary artery phantom for task-based CT performance assessment and a comparative study of clinical CT, photon counting CT, and micro CT
Jed D. Pack, Paul Fitzgerald, Stephen Araujo +7
While drastic improvements in CT technology have occurred in the past 25 years, spatial resolution is one area where progress has been limited until recently. New photon counting C…
Coronary Atherosclerotic Plaque Characterization with Photon-counting CT: a Simulation-based Feasibility Study
Mengzhou Li, Mingye Wu, Jed Pack +5
Recent development of photon-counting CT (PCCT) brings great opportunities for plaque characterization with much-improved spatial resolution and spectral imaging capability. While…
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…
Single-Shot Quantitative X-ray Imaging Using a Primary Modulator and Dual-Layer Detector
Linxi Shi, N. Robert Bennett, Alexander Vezeridis +2
Purpose: Conventional x-ray imaging and fluoroscopy have limitations in quantitation due to several challenges, including scatter, beam hardening, and overlapping tissues. In this…
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…
Deep Learning-Based Reconstruction of Interventional Tools from Four X-Ray Projections for Tomographic Interventional Guidance
Elias Eulig, Joscha Maier, Michael Knaup +4
Image guidance for minimally invasive interventions is usually performed by acquiring fluoroscopic images using a C-arm system. However, the projective data provide only limited in…
Detective quantum efficiency of photon-counting CdTe and Si detectors for computed tomography: a simulation study
Mats Persson, Adam Wang, Norbert J. Pelc
Purpose: Developing photon-counting CT detectors requires understanding the impact of parameters such as converter material, absorption length and pixel size. We apply a novel line…
