Evaluation of Silicon-Based Photon-Counting CT for Coronary Stenosis Quantification with Realistic Coronary Artery Phantoms
Maria Jose Medrano, Jed Pack, Stephen Araujo +5
Objective: To quantify the impact of high-resolution deep silicon photon-counting CT (dSi-PCCT) on coronary stenosis quantification in anatomically realistic calcified coronary art…
Protocol Optimization for Functional Cardiac CT Imaging Using Noise Emulation in the Raw Data Domain
Zhye Yin, Pengwei Wu, Ashish Manohar +2
Four-dimensional (4D) wide coverage computed tomography (CT) is an effective imaging modality for measuring the mechanical function of the myocardium. However, repeated CT measurem…
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…
