Patch-Probe Excitation for Ultrahigh Magnetic Field Wide-Bore MRI
IEEE Transactions on Microwave Theory and Techniques(2017)
Abstract
In this paper, we present the design of probe excitations for 7- and 10.5-T traveling-wave wide-bore magnetic resonance imaging systems. The probes are 297- and 447-MHz coaxially fed microstrip patches, designed to give a circularly polarized magnetic field when placed in the metallic bore waveguide. Images of a water phantom using the patch probes are obtained and compared with full-wave electrom...
