A comparative study of 1D and 3D hemodynamics in patient-specific hepatic portal vein networks

Popis výsledku v původním jazyce

The development of software for use in clinical practice is often associated with many requirements and restrictions set not only by the medical doctors, but also by the hospital's budget. To meet the requirement of reliable software, which is able to provide results within a short time period and with minimal computational demand, a certain measure of modelling simplification is usually inevitable. In case of blood flow simulations carried out in large vascular networks such as the one created by the hepatic portal vein, simplifications are made by necessity. The most often employed simplification includes the approach in the form of dimensional reduction, when the 3D model of a large vascular network is substituted with its 1D counterpart. In this context, a question naturally arises, how this reduction can affect the simulation accuracy and its outcome. In this paper, we try to answer this question by performing a quantitative comparison of 3D and 1D flow models in two patient-speci
