Abstract: 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.
Keywords: electromechanical analogy, modelling and simulation, dynamic fluid systems, haemodynamics, equivalent electromagnetic system, transmission line propagation characteristics
