An Object-Orient Designed FDTD simulator- applications to high field systems

An finite-difference time-domain (FDTD) simulator has been developed for electromagnetic analysis and design applications in 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 program has been constructed in an object-oriented framework. The design procedure is described and MRI-based numerical examples are provided to illustrate the utility of the numerical solver, particular emphasis is placed on high field examples
