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.
This article describes the author’s theory and practice in the field of transmission microwave CT and discusses the influence of various factors (environmental media, antenna beam, target properties, etc.) on imaging quality in microwave CT imaging. The CT model was acquired by the simple model and the CT images were obtained by using the program.The results of this paper show that the transmitted microwave CT can obtain reasonable image and resolution for low contrast targets and severe artifacts for high contrast targets, But still get valuable information.
