Decision Forests for Segmentation of the Left Atrium from 3D MRIing approach using decision forests that requires very few assumptions on the segmentation problem. First, we extract the blood pool using a simple thresholding technique. Then, we learn to separate the left atrium from other structures in the image by using context-rich features applied on images e

Hemodynamic in Aortic Coarctation Using MRI-Based Inflow Condition the focus of the 2013 STACOM Challenge. The focus of our study was inflow conditions. We compared a MRI-based inlet velocity profile with a swirl and an often used plug velocity profile without swirl. The unsteady flow simulations were performed using the solver FLUENT with consideration of the cha

Sensitivity Analysis of the Boundary Conditions in Simulations of the Flow in an Aortic Coarctation owing. Therefore, severe coarctations have important side-effects on the hemodynamic conditions of the circulatory system. The Computational Fluid Dynamics (CFD) simulation of the hemodynamics in a patient specific aortic coarctation can help to predict the pressure drop produced by the aorta narrow

Patient-Specific Hemodynamic Evaluation of an Aortic Coarctation under Rest and Stress Conditions to assist time-critical diagnostics or surgical decisions. Compared to high-fidelity pressure transducers, CFD offers flexibility to analyze baseline hemodynamic characteristics at rest but also under stress conditions without application of pharmacological stress agents which present undesirable s

A Multiscale Filtering-Based Parameter Estimation Method for Patient-Specific Coarctation Simulationssure data. In this work, a multiscale 0D-3D strategy is tested to match the given data. The 3D outlet boundary conditions for the supra-aortic vessels are represented by three-element Windkessel models. In order to estimate the Windkessel parameters at these outlets, a 0D lumped parameter model for

A Finite Element CFD Simulation for Predicting Patient-Specific Hemodynamics of an Aortic Coarctatiotudy was to predict the pressure gradient at rest and at exercise conditions. The commercial package ADINA was used to numerically solve the governing equations using finite-elements methods. The model was based on the patient’s MR angiography data. The boundary conditions imposed in the model inclu

Traditional CFD Boundary Conditions Applied to Blood Analog Flow through a Patient-Specific Aortic Ctry and prescribed flow conditions) were provided by the MICCAI-STACOM CFD Challenge website. The objective is to predict a blood pressure difference across the rigid coarctation under both rest and exercise (stress) conditions. The supplied STL geometry was used to create coarse and fine viscous me
