| 摘 要： | 根据微波近场乳腺癌检测仿真系统研究存在的问题,设计出一套比较完善的仿真软件。此次的更新点主要在于:1.加入了天线的线性极化设置;2.采用廖氏二阶吸收边界提高运算速率;3.能够实时观测电场或磁场的分布情况。采用confocal成像算法对仿真软件产生的数据进行处理,结果表明该软件产生的数据有效,能够用于今后成像算法的研究,对建立实际系统也有一定指导意义。

| Abstract: | An improved simulation system has been developed according to problems found in near field microwave detection for breast cancer.Advantages over the old system are: 1.polarization of the antennas now can be set or reset in the new system;2.Liao’s 2nd order absorbing boundary has been applied to simplify the boundary computation;3.Para-view for the electric and magnetic fields is obtained.The imaging result with confocal algorithm demonstrates that data created by this simulation system are effective.It will be helpful for studying microwave imaging algorithms and building realistic system in the future. |
