Application of Microwave on Undestructively Detecting Leukemia:The Numerical Simulation

已有研究结果表明，癌变骨髓与正常骨髓介电特性存在明显差异，利用微波对白血病进行无损探测及治疗过程的监测是完全可行的。本文在建立柱坐标系下人体小腿上部微波散射特性的分析模型基础上，具体计算了多种频率下人体小腿上部的微波散射特性及与白血病病变程度的关系，探讨了探测源的最佳工作频率及其最佳位置、接收传感器的最佳位置等问题。该技术可应用于白血病的无损探测及治疗过程的监测中，而微波散射特性的分析有助于解决微波成像的实时性难题。

Many researchers Proved that it is feasible to detect leukemia or monitor the treatment of leukemia by using microwave. In this paper, calculations of the microwave scattering from the upper part of the lower leg with the presence of leukemia at various frequencies have been given based on the FDTD modeling in the cylindrical coordinate system. The optimal frequency as well as the optimal location of the source and the sensor have also been discussed. The results are helpful in realizing real-time microwave imaging of leukemia.
