Originální abstrakt

The contribution presents a perspective approach to increasing the sensing coil's working range in magnetic resonance imaging using a planar resonant structures with distributed parameters. The working range increase consists in the improvement of homogeneity of the RF magnetic field generated by the coil. In the contribution, a novel resonant structure – Grid Quasi-Periodic Resonant structure, is introduced. Results of numerical modeling of the structure are presented. The results indicate significant improvement of the magnetic field homogeneity in selected area. In order to verify the simulation results, a test structure has been fabricated and it has undergone experimental measurement. The results of the measurement are in a good agreement to simulation results.
