这项工作的重点是通过微波技术进行脑卒中成像。具体地说，为了给临床医生提供一种工具，在随访期内控制所用治疗的有效性，这里讨论了中风发病后监测患者的公开问题。本文提出了一种新的原型，并对其进行了表征。该设备基于一种低复杂性的架构，该架构利用了放置在头盔上的最少数量的正确定位和设计的天线。它利用了一种差分成像方法，并提供了中风的3D图像。对一个充满脑组织模拟液体的3D模型进行的初步实验证实了该技术在对半径为1.25厘米的中风进行球形目标成像方面的潜力。
This work focuses on brain stroke imaging via microwave technology. In particular, the open issue of monitoring patients after stroke onset is addressed here in order to provide clinicians with a tool to control the effectiveness of administered therapies during the follow-up period. In this paper, a novel prototype is presented and characterized. The device is based on a low-complexity architecture which makes use of a minimum number of properly positioned and designed antennas placed on a helmet. It exploits a differential imaging approach and provides 3D images of the stroke. Preliminary experiments involving a 3D phantom filled with brain tissue-mimicking liquid confirm the potential of the technology in imaging a spherical target mimicking a stroke of a radius equal to 1.25 cm.
