The idealized three-dimensional computational model of a saccular cerebral aneurysm is used to study vascular hemodynamics under the effect of external electromagnetic fields. Magnetic resonators emit the analyzed fields with different application directions on the patient in the dorsal decubitus position. Computational simulation of two resonator configurations evaluates the effect of the magnetic field direction on blood velocity and particle residence time. Results show that an open resonator allows faster fluid entry into the aneurysm sac and significantly increases particle residence time within the domain.
