Advances towards the Development of a Brain Microwave Imaging Scanner

摘要

This paper presents some hardware advances towards a microwave system for brain imaging. In particular, we present a new antenna array design for efficient propagation of microwave signals in the head, as well as a metamaterial structure designed for transmission enhancement through impedance matching. The presented system is modelled in CST Microwave Studio^®, using a specific anthropomorphic mannequin (SAM) head model to analyse performance. Simulations results suggest that our designs can be useful in designing a microwave scanner for brain imaging applications such as stroke detection and monitoring.
