利用微波进行计算机辅助断层成象

本文叙述作者在传输型微波CT方面做的理论和实践工作,讨论了微波CT成象中各种因素(环境媒质、天线波束、目标性质等)对成象质量的影响.建立了实验装置,对简单模型采集了CT数据,运用所编程序获得了CT图象.本文的结果表明:传输型微波CT对低反差目标能得到合理的图象和分辨率,对高反差目标虽有严重伪象,但仍可获得有价值的信息.

MICROWAVE COMPUTERIZED TOMOGRAPHY

In this paper, the theory and practice of transmission microwave OT performed by the authors are stated. How the various factors in microwave OT imaging effect the quality of image is discussed. The tomography scanner apparatus were established and OT-date of simple phantoms were collected. Using the reconstructive program, we nave got the microwave OT images. It is shown that we can get suitable image and resolution for low contrast objects, and valuable information for high contrast objects though the pseudomorph. appears seriously.
