The purpose of this study was to construct a microwave tomographic system capable of conducting experiments with whole scale biological objects and to demonstrate the feasibility of microwave tomography for imaging such objects using a canine model. Experiments were conducted using a three-dimensional (3-D) microwave tomographic system with working chamber dimensions of 120 cm in diameter and 135 cm in height. The operating frequency was 0.9 GHz. The object under study was located in the central area of the tomographic chamber filled with a salt solution. Experimentally measured attenuation of the electromagnetic field through the thorax was about -120 dB. To obtain images, we used various two-dimensional and 3-D reconstruction schemes. Images of the canine were obtained. In spite of imperfections, the images represent a significant milestone in the development of microwave tomography for whole body imaging and demonstrate its feasibility.
本研究的目的是构建一个能够对全尺寸生物对象进行实验的微波断层扫描系统，并使用犬类模型证明微波断层扫描对这类对象成像的可行性。实验使用了一个三维（3-D）微波断层扫描系统，其工作室尺寸为直径120厘米、高135厘米。工作频率为0.9吉赫兹。所研究的对象位于充满盐溶液的断层扫描腔室的中心区域。通过实验测量，穿过胸部的电磁场衰减约为-120分贝。为了获得图像，我们使用了各种二维和三维重建方案。获得了犬类的图像。尽管存在缺陷，但这些图像代表了用于全身成像的微波断层扫描发展中的一个重要里程碑，并证明了其可行性。
