本文介绍了利用动态微波-雷达成像系统进行乳腺癌对比增强检测的数值研究。利用三维异质乳房模型,我们提出了基于全波电磁模拟的全面可行性研究。计算结果表明,由于摄取造影剂,癌症组织的平均电学性质即使有1%的变化,也足以用微波雷达系统探测到。作为造影剂,我们考虑金纳米颗粒。我们的结果表明,纳米颗粒可以在临床相关浓度中提供可检测到的变化。
This paper presents numerical studies of contrast-enhanced breast cancer detection using dynamic microwave-radar imaging system. Using three-dimensional heterogeneous breast models, we present a comprehensive feasibility study based on full-wave electromagnetic simulations. Computational results reveal that even a 1% change in the average electrical properties of cancerous tissues due to the uptake of the contrast agent is sufficient to be detected using the microwave radar system. As the contrast agent we consider gold nanoparticles. Our results suggest that nanoparticles could provide detectable changes in clinically relevant concentrations.
