Modelling and calculation of influences of RF-fields on the human body using the finite element method
Calculating eddy current effects in the human body requires a more or less simplified model when using the finite element method (FEM). A well known 3D-formulation for low frequency eddy currents has been employed. The way chosen to find a model feasible for FEM techniques without neglecting the mos...

| description | Calculating eddy current effects in the human body requires a more or less simplified model when using the finite element method (FEM). A well known 3D-formulation for low frequency eddy currents has been employed. The way chosen to find a model feasible for FEM techniques without neglecting the most important organic influences on the eddy currents will be described. A final model has been analysed and the results have been compared with measured ones obtained by MR-imaging.< > |
