| 摘 要： | 研究了利用微波检测白血病及监测白血病治疗过程的有关理论和技术。用ＦＤＴＤ法分析了当微波源采用 ８００ ＭＨｚ的无限长均匀线电流源和电偶极子天线时，人体小腿上部电磁散射特性与骨髓癌变程度的关系。数值结果表明，当采用电偶极子天线作为微波源时，可以获得较佳的分辨率及检测灵敏度。

| Abstract: | In this paper, the technique of detecting leukemia and monitoring its treatment by microwave is presented. Two types of microwave source with operating frequency 800 MHz, i.e., line source and shorter antenna are considered. The finite-difference time-domain(FDTD) method is used to investigate the scattering field as the functions of the pathological degree of leukemia. The analysis shows that the better distinguishability and detective sensitivity can be obtained when shorter antenna is employed as microwave source. |
