Several methods have been proposed to analyze
hemodynamic parameters from 4D flow data, including
vorticity and helicity. However the analysis is usually
qualitative and performed in reformatted 2D planes. In
this work we propose a novel method that integrates
advanced image processing strategies and computational
techniques based on finite element interpolations to
obtain a 3D quantitative map of vorticity, helicity
density and relativity helicity density derived from 4D
flow data sets obtained from volunteers and patients.
