Modeling and Experimental Didactic Solution for Analysing the Arterial Stenosis

This paper presents a didactic solution for arterial stenosis analysis that contains mathematical modelling, practical implementation and functional simulation which can provide an easy learning solution for medical, biomedical engineering, or other related branches of students and researchers. For this purpose, several steps are followed, starting with an image captured from an angiography. With the aid of a dedicated software, a mesh will be created, and after a CAD defeaturing process, the blood vessel model will be imported in a simulation program, where real conditions will be analyzed. The next step consists in implementing a flow phantom that will be used for functional simulations. The experimental artery segment will be included in the experimental setup, allowing closer analysis of the pressure by controlling the fluid flow parameters in the probe. With the help of a data acquisition board, signals from the sensors are acquired, processed and displayed using the virtual instrument. Results obtained from mathematical modelling are presented along with user interface captures from two distinct experimental simulations with imposed parameters through the electronic control unit: adjustable fluid flow and pulse sensor synchronized fluid flow.
