RESUMO
Objective To put forward a method for 3D electrical impedance finite element joint modeling and simulation using COMSOL for visual modeling and Visual C++ for programming.Methods A model was established with COMSOL,and then transformed into a.stl file and introduced into Visual C++ simulation platform.Delaunay tetrahedral mesh generation algorithm was used for finite element meshing,calculation and simulation,and joint modeling and simulation were realized finally.Results Simulation result showed that the method could be used to introduce COMSOL model and complete 3D finite element simulation.Conclusion The method proves its compatibility with the models generated by multi software and practicability for joint modeling and simulation.

RESUMO
Objective To realize K space image reconstruction by using VC++ and Matlab in the development of MRI software.Methods VC++ called FFT(Fast Fourier Transform Algorithm) function of matlab math dlls to realize transforming the data from k space to real space.Results Image reconstruction was realized successfully for the clinical demand.The development circle and programming workload were greatly reduced.Conclusion The mixed programming by VC++ and Matlab can reduce the developing process and improve the reliability of the software.
