Evaluating an algorithm for 3D reconstruction of blood vessels for further simulations of hemodynamic in human artery branches

We aimed at verification of a novel algorithm for semiautomatic reconstruction of the branches of human aortic arch for blood perfusion analysis used later in the Computational Fluid Dynamic (CFD). The algorithm works on initially adjusted CT scans divided into segments. Obtained binary segmentation results were next checked manually and corrected if needed. The final reconstruction was used for preparation of a numerical grid and for further calculation of blood hemodynamic. The collected data composed of blood velocity and blood flow rate in function of time were compared with USG-Doppler data. Preliminary results demonstrate that proposed algorithm may be useful for initial reconstruction of human cardiac system, however its accuracy needs to be improved as further manual corrections are still needed.
