Abstract
A possibility of using the 4D Qflow protocol, which is commonly used for medical diagnostics in magnetic resonance imaging, for determining the structure of the three-dimensional fluid flow in the human blood circulation system is considered. Specialized software is developed for processing DICOM images obtained by the magnetic resonance scanner, and the retrieved unsteady three-dimensional velocity field is analyzed. It is demonstrated that magnetic resonance measurements allow one to detect the existence of the flow in blood vessel models and also to study the degree of its swirling (helicity) both qualitatively and quantitatively.
