Towards a microwave imaging device for cerebrovascular diseases monitoring: from numerical modeling to experimental testing

This chapter presents the design, realization, and validation of a fullfledged device for imaging-based detection and monitoring of cerebrovascular diseases via microwave technology. The designed system is a compact and lowcomplexity prototype with a wearable twenty-two-element antenna array able to perform continuous real-time follow-up of a brain stroke evolution. The imaging algorithm exploits a differential scheme that receives the scattering matrices collected at two different instants and reconstructs tridimensional images relying on the distorted Born approximation. Furthermore, it employs the singular value decomposition of the discretized scattering operator computed via full-wave simulations of high-realistic models and an EM solver based on an in-house finite element method.
