摘要
论述多频阻抗断层成像(MFEIT)数据采集系统中电极频率特性对重构图像的影响,并进行了数据分析和验证实验,进而提出数据预处理方法。经过预处理的数据重构出的图像显著削弱了电极影响,这一结果表明了设计出的数据预处理方法的有效性。
The impact of the electrode frequency characteristic on the reconstructed image in MFEIT is studied.Data analysis and validation experiments are devised,a pretreating method for muli-frequency data is proposed as well.The revised experiment result shows the effect of the electrode frequency characteristics is notably reduced.The results indicate the method described is effective.
