Although tube current modulation (TCM) is routinely implemented in modern computed
tomography (CT) scans, no existing CT simulator is capable of generating realistic images …

OBJECTIVE. The virtual imaging trial is a unique framework that can greatly facilitate the
assessment and optimization of imaging methods by emulating the imaging experiment …

Background CT scan has notable potential to quantify the severity and progression of
emphysema in patients. Such quantification should ideally reflect the true attributes and …

Background Quantitative analysis of computed tomography (CT) images traditionally utilizes
real patient data that can pose challenges with replicability, efficiency, and radiation …

CT imaging has proved to be an effective tool in evaluating COPD patients. The
development of photon-counting detectors has offered better spatial resolution and reduced …

Virtual imaging trials (VITs), defined as the process of conducting clinical imaging trials
using computer simulations, offer a time-and cost-effective alternative to traditional imaging …

The purpose of this study was to develop a virtual imaging framework that simulates a new
photon-counting CT (PCCT) system (NAEOTOM Alpha, Siemens). The PCCT simulator was …
