Incorporating phase retardation effects into radiofrequency resonator models: application to magnetic resonance microscopy
journal contribution
posted on 2023-05-16, 12:01 authored by Crozier, S, Lawrence ForbesLawrence Forbes, Roffmann, WU, Luescher, K, Doddrell, DMA method is presented for including path propagation effects into models of radiofrequency resonators for use in magnetic resonance imaging. The method is based on the use of Helmholtz retarded potentials and extends our previous work on current density models of resonators based on novel inverse finite Hilbert transform solutions to the requisite integral equations. Radiofrequency phase retardation effects are most pronounced at high field strengths (frequencies) as are static field perturbations due to the magnetic materials in the resonators themselves. Both of these effects are investigated and a novel resonator structure presented for use in magnetic resonance microscopy.
