摘要
基于有限元法对电容-电阻双模态成像系统中的敏感场电磁特性进行分析。分别推导出电容层析成像和电阻层析成像中敏感场的数学模型和等价泛函,并对敏感场电磁特性进行有限元法解析,将分析的电位值进行三维图形化,为进一步研究电容-电阻双模态成像系统的图像重建提供了有意义理论和实验支持。
The electromagnetic characteristic of sensitive field of Electrical Capacitance-Resistance Tomography two modes system based on Finite Element Method is analysed.The mathematic model of sensitive field of electrical capacitance tomography and electrical resistance tomography is deduced respectively,then the electromagnetic characteristic of sensitive field is evaluated using Finite Element Method,and the voltage functions is ploted by three dimension figure.It is helpful for researching on image reconstruction of Capacitance-Resistance Tomography two modes system.
