Development of Novel Cardiac CT Methods
… 1 in every 2.7 deaths was associated with CVD. Cardiac CT has become a very valuable tool for non-invasive CVD diagnosis due to enabling technologies like helical scanning, fast rotation, multi-row detector, and advanced image reconstruction. However, challenges like cone-beam artifact …

Model-based cardiac CT segmentation and 3D heart reconstruction
… is a serious disease in human beings. An effective way to cure liver cancer is the liver transplant operation. However, to make the surgical plan, the doctors need to know the structure, location and thickness of the hepatic vein. Therefore, hepatic vein segmentation is an initial and crucial …

Universal Atrial Coordinate (UAC) for Wall Motion Deep Learning
… framework for LA wall motion analysis using 4D cardiac CT in both sinus rhythm (SR) and AF. LA geometries were segmented, temporally aligned via Coherent Point Drift (CPD) registration, and mapped to a 2D Universal Atrial Coordinate (UAC) system. Wall motion, quantified from Signed Distance …

Advanced Applications of Cardiac Computed Tomography for the Difficult-to-Image Patient
… 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 …

Detection and prediction of cardiac quiescence for computed tomography coronary angiography
The objective of this work is to improve the diagnostic quality and reduce the radiation dose of computed tomography coronary angiography (CTCA) imaging by developing gating techniques based on signals derived from cardiac motion, rather than the currently used electrocardiogram (ECG), to more …

Improving Cardiovascular Risk Assessment with CT Coronary Angiography and Myocardial CT Perfusion
… risk in various clinical settings. CT coronary angiography (CTCA) and myocardial CT perfusion (CTP) are promising techniques for the assessment of these factors. This thesis is comprised of several projects which explore refinements and new techniques aimed at improving diagnosis and …
