A Microwave Tomography System For Ischemic Stroke Based on Distorted Born Iterative Method

This paper presents a microwave tomography system for ischemic stroke. The developed device consists of a measurement prototype, a matrix switch and a vector network analyzer(VNA). and it equipped with an efficient imaging method for the reconstruction of the distribution of the relative permittivity of the human body under test. It has been preliminarily verified by experimental data. The results show that the system can effectively detect inclusions with different sizes and positions in the head model under consideration.
