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。 The related theories and techniques for microwave detection of leukemia and monitoring of leukemia treatment were studied. The FDTD method was used to analyze the relationship between the electromagnetic scattering of the upper part of the human lower leg and the degree of myelocarcinogenesis of the bone marrow when an 800 MHz infinite uniform current source and an electric dipole antenna were used as the microwave source. The numerical results show that when the electric dipole antenna is used as a microwave source, better resolution and detection sensitivity can be obtained.
