Temporal interpolation of 4D PC-MRI blood-flow measurements using bidirectional physics-based fluid simulation

Our PatchMove system discards the Temporal Coherence term used in the original PatchMatch framework, because patch- based interpolation with our bidirectional greedy modifi-

This includes an automated data preprocessing, a graph cut-assisted vessel segmentation, semi-automatic vortex flow extraction and analysis of the stroke volume as well as

Moreover, the calculated vortex properties should reflect and extend the binary expert classifications accord- ing to minor and pronounced flow or helix and vortex.. Besides a

“Accurate noninvasive quantitation of blood flow, cross-sectional lumen vessel area and wall shear stress by three-dimensional paraboloid modeling of magnetic resonance imaging

We evaluated our method, using synthetic flow data and high resolution measurements, to assess the interpolation quality, com- paring for velocity magnitude, curl

To approximate LCS in our discrete images, we employ Finite Time Lyapunov Exponent (FTLE) fields to quantify the rate of separation of neighboring flow trajectories1. LCS appear

Existing straightforward 3D visualizations, such as surface or volume rendering do not work well when using the magnitude data of the PC-MRI measurement as a basis for
