Experimental Assessment of Real-Time Brain Stroke Monitoring via a Microwave Imaging Scanner

This paper presents the experimental validation of a microwave imaging system for real-time monitoring brain stroke in post-acute stage. The exploits low-complexity sensing apparatus and multi-frequency algorithm with novel artifact removal feature. Phantoms homogeneous anthropomorphic head an ellipsoidal non-static mimicking target, varying gradually from 0 cm3 to 60 cm3, are employed experiments. phantom evolving target filled appropriate alcohol-based mixtures mimic different dielectric properties relevant tissue. scanner operates using 22-antennas architecture formed by printed flexible antennas custom-made matching medium. provides 3-D images entire region, exploiting differential multi-view scattering measures distorted Born approximation build pre-computed kernel. results show system’s capability follow up continuous progression hemorrhage ischemia zones centimetric spatial resolution provide information on whether is growing or shrinking.
