A Survey of Cardiac 4D PC‐MRI Data Processing
(© 2017 The Eurographics Association and John Wiley & Sons Ltd., 2017)
Cardiac four‐dimensional phase‐contrast magnetic resonance imaging (4D PC‐MRI) acquisitions have gained increasing clinical interest in recent years. They allow to non‐invasively obtain extensive information about ...
Visual and Quantitative Analysis of Great Arteries' Blood Flow Jets in Cardiac 4D PC-MRI Data
(The Eurographics Association and John Wiley & Sons Ltd., 2018)
Flow in the great arteries (aorta, pulmonary artery) is normally laminar with a parabolic velocity profile. Eccentric flow jets are linked to various diseases like aneurysms. Cardiac 4D PC-MRI data provide spatio-temporally ...
Robust Cardiac Function Assessment in 4D PC‐MRI Data of the Aorta and Pulmonary Artery
(Copyright © 2016 The Eurographics Association and John Wiley & Sons Ltd., 2016)
Four‐dimensional phase‐contrast magnetic resonance imaging (4D PC‐MRI) allows the non‐invasive acquisition of time‐resolved, 3D blood flow information. Stroke volumes (SVs) and regurgitation fractions (RFs) are two of the ...
Visualization of Cardiac Blood Flow Using Anisotropic Ambient Occlusion for Lines
(The Eurographics Association, 2017)
Ambient occlusion (AO) for lines (LineAO) was introduced by Eichelbaum et al. [EHS13] as an adaption of screen-space AO to static line bundles, such as white brain matter fiber tracts derived from diffusion tensor imaging ...
Pressure-based Vortex Extraction in Cardiac 4D PC-MRI Blood Flow Data
(The Eurographics Association, 2018)
We propose a technique for vortex extraction in cardiac 4D PC-MRI blood flow data that employs an intravascular, relative pressure calculation. The method is easy to implement, runs fully automatically, and requires no ...
Guided Analysis of Cardiac 4D PC-MRI Blood Flow Data
(The Eurographics Association, 2015)
Four-dimensional phase-contrast magnetic resonance imaging (4D PC-MRI) allows the non-invasive acquisition of temporally resolved, three-dimensional blood flow information. Quantitative and qualitative data analysis helps ...
Robust Cardiac Function Assessment in 4D PC-MRI Data
(The Eurographics Association, 2014)
Four-dimensional phase-contrast magnetic resonance imaging (4D PC-MRI) is a relatively young image modality that allows the non-invasive acquisition of time-resolved, three-dimensional blood flow information. Stroke volumes ...
A Survey of Cardiac 4D PC-MRI Data Processing
(The Eurographics Association, 2015)
Cardiac 4D PC-MRI acquisitions gained increasing clinical interest in recent years. They allow to non-invasively obtain extensive information about patient-specific hemodynamics and thus have a great potential to improve ...
Semi-Automatic Vessel Boundary Detection in Cardiac 4D PC-MRI Data Using FTLE fields
(The Eurographics Association, 2016)
Four-dimensional phase-contrast magnetic resonance imaging (4D PC-MRI) is a method to non-invasively acquire in-vivo blood flow, e.g. in the aorta. It produces three-dimensional, time-resolved datasets containing both flow ...
Semi-automatic Vortex Flow Classification in 4D PC-MRI Data of the Aorta
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
We present an Aortic Vortex Classification (AVOCLA) that allows to classify vortices in the human aorta semi-automatically. Current medical studies assume a strong relation between cardiovascular diseases and blood flow ...
