FVTD-based analysis of brain stroke response in microwave imaging systems

Description

In this paper, a numerical analysis of the electromagnetic response of brain strokes when illuminated by the incident radiation used in microwave imaging systems is performed. In particular, a two dimensional simulator based on the Finite-Volume Time-Domain (FVTD) method is used in order to efficiently solve the forward scattering problem in the presence of complex structures. Moreover, an anatomically realistic head phantom, obtained from Magnetic-Resonance images, is employed for simulating the biomedical configuration. The electromagnetic field propagation inside the head tissues is investigated and the effects of the presence of the stroke on the scattered field (collected at the measurement points) are evaluated.
