微波成像是基于材料的电特性（介电常数和电导率）差异。用于生物医学应用的微波成像特别有趣，主要是由于不同组织的介电特性的可用范围可以提供关于其健康的重要功能信息。在假设3D散射问题可以合理地表示为简化的2D模型的情况下，可以利用2D模型的简单性和较低的计算成本来表征这种3D现象。尽管如此，通过消除过度的模型简化，3D微波成像提供了比2D技术更有价值的信息，因此，可以获得更准确的介电特性图。在本文中，我们提出了一些进展，我们已经在三维图像重建，并显示从三维乳房体模实验的结果，使用我们的临床微波成像系统在达特茅斯希区柯克医疗中心（DHMC），NH。
Microwave imaging is based on the electrical property (permittivity and conductivity) differences in materials. Microwave imaging for biomedical applications is particularly interesting, mainly due to the fact that available range of dielectric properties for different tissues can provide important functional information about their health. Under the assumption that a 3D scattering problem can be reasonably represented as a simplified 2D model, one can take advantage of the simplicity and lower computational cost of 2D models to characterize such 3D phenomenon. Nonetheless, by eliminating excessive model simplifications, 3D microwave imaging provides potentially more valuable information over 2Dtechniques, and as a result, more accurate dielectric property maps may be obtained. In this paper, we present some advances we have made in three–dimensional image reconstruction, and show the results from a 3D breast phantom experiment using our clinical microwave imaging system at Dartmouth Hitchcock Medical Center (DHMC), NH.
