1. 1. Semi-Automatic Analysis and Visualization of Cardiac 4D Flow CT

   University essay from Linköpings universitet/Institutionen för hälsa, medicin och vård

   Author : Anthony van Oosten; [2022]
   Keywords : 4D CT; CT; 4D flow; Flow Component Analysis; Singular value decomposition; left atrial appendage; LAA; CFD; 3 chamber view; computed tomography; maximum outflow velocity; volume rendered CT; semi-automatic; visualization; flow visualization; cardiac views; semi-automatic analysis; semi-automatic visualization; visualization of 4D flow;

   Abstract : The data obtained from computational fluid dynamics (CFD) simulations of blood flow in the heart is plentiful, and processing this data takes time and the procedure for that is not straightforward. This project aims to develop a tool that can semi-automatically process CFD simulation data, which is based on 4D flow computed tomography (CT) data, with minimal user input. READ MORE

3. 2. Visualization and Quantification of Helical Flow in the Aorta using 4D Flow MRI

   University essay from Linköpings universitet/Institutionen för medicinsk teknik

   Author : Filippa Gustafsson; [2016]
   Keywords : Helical flow; Helicity density; LNH; 4D Flow MRI; geometry of the aorta;

   Abstract : Due to the complex anatomy of the heart, heart valves and aorta, blood flow in the aorta is known to be complex and can exhibit a swirling, or helical, flow pattern. The purpose of this thesis is to implement methods to quantify and visualize both the speed of helicity, referred to as the helicity density, and the direction of helicity, which is measured by the localized normalized helicity.

4. 3. Segmentation of the cardiovascular tree in 4D from PC-MRI images

   University essay from Lunds universitet/Matematik LTH

   Author : Peter Öberg; [2013]
   Keywords : Fourflow; Segment flow; PC-MRI; visualization; 4D; flow; Cardiovascular tree; noise reduction; Mathematics and Statistics; Medicine and Health Sciences;

   Abstract : Investigating the dynamics of blood flow is essential to understanding the cardiovascular system and its pathologies. Phase Contrast Magnetic Resonance Imaging (PC-MRI) enables acquisition of 4-dimensional time resolved velocity experiments. Slice-by-slice analysis of the data is time consuming and cumbersome.
