应用经准直的频率为10.5千兆的微波替代X线束来重建CT图象已获成功。在作者的实验室里是使用一台旋转一平移扫描机和固定的微波源。被测物体在微波源和探测器之间移动。被测物体悬吊在盛有聚乙二醇(Polythylene glycol[PEG],分子量为400)液体的箱体中,以使被测物体、微波源和接收器之间的阻抗匹配。被测物体(模型)由盛水 It has been successful to reconstruct CT images using collimated 10.5-GHz microwaves instead of X-ray beams. In the author’s lab, a rotary-translation scanner and a fixed microwave source were used. The measured object moves between the microwave source and the detector. The object to be measured is suspended in a container filled with liquid polyethylene glycol (PEG) with a molecular weight of 400 to match the impedance between the object under test, the microwave source and the receiver.
