摘要

The paper deals with modelling and simulation of a human brain arterial system using analogous electromagnetic systems, especially propagation characteristics of electric transmission lines. Cascade connection of analogous equivalent transmission line elements represents a vessel tree concerning both the electromagnetic parameters and the topology. Electromechanical analogy between physiological and electromagnetic values enables a description and following simulation of a cerebral haemodynamics by means of electric circuits analogous relations. The vascular dynamics modelling and simulation represents an important tool for the non-invasive computer-aided investigation of the brain arteries pathological deformations. The presented simulation results give the information about the blood dynamic characteristics also in the case of cerebral arterial stenoses or aneurysms under various stenosis degrees. The obtained results can provide helpful knowledge for the practical treatment of the basic brain arteries.
