The main research goal is to enhance the spatial resolution of state-of-the-art Microwave Tomography (MWT) systems for biomedical imaging. MWT is a relatively new modality that uses microwave measurements to create a quantitative image of the bulk-electrical material properties of biological tissues situated in a body. Although some recent results for breast cancer imaging are impressive, MWT has not become the modality of choice for any biomedical application. This is mostly due to the limited spatial resolution of the current state-of-the-art. But there are many potential advantages of MWT, including (1) its low cost and portability; (2) its use of safe non-ionizing radiation; and (3) its ability, without contrast agents, to create quantitative images of the dielectric constant and conductivity of living tissue as a way of identifying physiological conditions of

主要研究目标是提高最先进的微波断层扫描（MWT）系统的空间分辨率，用于生物医学成像。MWT是一种相对较新的模式，它使用微波测量来创建位于体内的生物组织的体电材料特性的定量图像。尽管最近乳腺癌成像的一些结果令人印象深刻，但MWT尚未成为任何生物医学应用的首选模式。这主要是由于当前最先进技术的有限的空间分辨率。但是MWT有许多潜在的优点，包括（1）其低成本和便携性;（2）其使用安全的非电离辐射;以及（3）其在没有造影剂的情况下创建活组织的介电常数和电导率的定量图像的能力，作为识别活体组织的生理状况的一种方式。
