本文介绍了用于脑中风检测的微波断层扫描系统的数值分析。该系统由充满液体模型的八角形容器组成，该液体模型具有人体头部的平均介电参数。集装箱壁上有八个槽领结天线。该系统进行了数值建模和评估。根据分析，可以考虑对系统的物理实现进行修改，并且应该会导致未来版本的更好设计。分析包括观察容器内部 E 场的分布、评估 S 参数矩阵以及系统对出血性中风幻影存在的响应。最后将图像重建算法应用于S参数矩阵并给出重建结果。
In this paper numerical analysis of a microwave tomography system for brain stroke detection is presented. This system is composed from octagonal container filled with liquid phantom having the average dielectric parameters of human head. On the walls of the container, there are eight slot bow tie antennas. This system was numerical modelled and evaluated. According to the analysis, modification in physical realization of the system can be considered and should lead to a better design of the future version. The analysis includes observation of distribution of E field inside of the container, evaluation of S parameter matrix and response of the system to a presence of a phantom of haemorrhagic stroke. Image reconstruction algorithm is finally applied on the S parameter matrix and the results of reconstruction are presented.
