An object-oriented designed finite-difference time-domain simulator for electromagnetic analysis and design in MRI.
This paper presents a finite-difference time-domain (FDTD) simulator for electromagnetic analysis and design applications in magnetic resonance imaging (MRI). It is intended to be a complete FDTD model of an MRI system including all RF and low frequency field generating units and electrical models of the patient. The framework has been constructed with the assistance of object-oriented concepts. The detailed design procedure is described and the numerical method has been verified against analytical solutions for simple cases and also applied to real field calculations. The simulated results demonstrated that the proposed FDTD scheme can be used to analyze large-scale computational electromagnetic problems in MRI engineering.
