Current software used to process 4D Flow MRI data only allow to quantify a few hemodynamics parameters. Furthermore, the information of these parameters is normally given in a few 2D locations. In this work, we show the development of a novel, free and editable MATLAB toolbox (MathWorks, Natick, MA, USA) called FEMQ-4D that allows the quantification of several hemodynamic parameters in 3D using finite elements (FE) methods. As a complement to this tool, the output of FEMQ-4D, i.e 3D maps of hemodynamic parameters, can be visualized using the open source software PARAVIEW (KitwareInc., Clifton Park, New York, USA).
