| Abstract: | The paper proposes a new approach to compute the stray magnetic field of an MRI scanner. First the simplified model of MRI coils is created. The model should accurately simulate the stray magnetic field while being highly simplified and thus saving significantly the numerical resources. The simplified, analytical model is created by solving an inverse problem. Two inverse problem solvers: Levenberg-Marquardt and Particle Swarm Optimization are compared in this work. |
