Algorithms for Tomographic Reconstruction: Fast Back Projection and Cardiac Computed Tomography
The second problem we address is that of the reconstruction of a movie of the moving heart from fan-beam tomographic projections. We consider the problem within a state-space framework and present a reconstruction algorithm based on the ensemble Kalman filter. The algorithm reconstructs a movie of …

Advanced Applications of Cardiac Computed Tomography for the Difficult-to-Image Patient
Throughout the development of computed tomographic (CT) imaging the challenges of capturing the heart, with its perpetual, vigorous motion, and in particular the tiny detail within the coronary arteries, has driven technological progress. Today, CT is a widely used and rapidly growing modality for …

IMPACT OF STRESS CARDIAC COMPUTED TOMOGRAPHY MYOCARDIAL PERFUSION ON DOWNSTREAM RESOURCES AND PROGNOSIS IN PATIENTS WITH SUSPECTED OR KNOWN CORONARY ARTERY DISEASE: A MULTICENTRE INTERNATIONAL STUDY - THE CTP-PRO STUDY
Background: Stress computed tomography perfusion (Stress-CTP) is a CT-based functional technique that can be added to coronary computed tomography angiography (cCTA) to improve management of patients with suspected coronary artery disease (CAD). The aim of the study is to evaluate the usefulness of …

TO FACIAL FEATURES AS A NEW BIOMARKER FOR EARLY IDENTIFICATION OF HIGH-RISK ATHEROSCLEROSIS: A TRANSLATIONAL APPROACH
Introduction Cardiac computed tomography (CCT) emerged as a valuable non-invasive tool for early identification of high-risk coronary atherosclerosis. However, no validated biomarkers or scores are available to identify patients who may benefit from CCT in primary prevention. Aim of the present …

Association of Aortic Vascular Stiffness with Epicardial and Pericardial Adipose Tissues on 64-Multidetector Computed Tomography : In Relation with Coronary Atherosclerosis
… years, 78% male, underwent 64-multidetector row cardiac computed tomography (MDCT) and their carotid-radial pulse wave velocity (PWV) was measured using SphygmoCor tonometry. EAT and total thoracic adipose tissue (TAT) volumes were measured using MDCT. PAT was calculated as TAT – EAT. The highest …

A Scheme for Ultra-Fast Computed Tomography Based on Stationary Multi-Beam X-ray Sources
The current cardiac computed tomography (CT) technology is mainly limited by motion blurring and radiation dose. The conceptual multi-source interior CT scheme has provided a potential solution to reduce motion artifacts and radiation exposure. This dissertation work conducted multi-facet …

Design of x-ray source for real-time computed tomography
<p>"The reduction of motion blur in computed tomography (CT) drives the current research for multisource CT. Due to their compact nature, the current multisource systems utilize stationary angled anodes. Unfortunately, these configurations neither simplify the imaging geometry, nor satisfy the need …
