Assessment of 4D flow of the brain using MRI.

Recently, we have developed various tools for quantifying 4D flow in the main vessels of the cardiovascular system. These tools allow us to obtain different parameters, including wall shear stress, vorticity, helicity, kinetic energy, and many others. The process of quantifying 4D flow involves pre-processing the data (removing noise and applying correction methods), segmenting the data, creating a finite element mesh, and finally performing the parameter calculations on the 3D finite element mesh. The aim of this project is to adapt these tools to assess 4D flow in the brain. The project will involve developing tools for data filtering, automatic vessel segmentation, creating strategies for super-resolution, and testing the accuracy of the quantification methods.
