| Abstract: | This paper describes an emulation software package for capacitance tomographic image reconstruction which is based on 12 electrode capacitance transducers. It is developed on SGI graphic workstation using visualization programming language PV WAVE. With the help of it, we are able to have the in depth study of the changing of capacitance sensitivity distributions and fluid model parameters. Hence, it provides powerful methods for improving image reconstruction algorithm and the design of optimal capacitance transducer geometrical parameters. Finally, by using the emulation results, the properties of capacitance tomography are discussed. |
