Abstract:
To provide an RF coil of an MRI apparatus and improve the irradiation efficiency and the reception sensitivity of a circular polarized magnetic field with a simple structure.An RF coil has a set of input/output terminals and two loops. The two loops are disposed and capacitors in the loops are adjusted so that the linearly polarized magnetic fields generated and detected by the loops are perpendicular to each other, and the combined magnetic field of the linearly polarized magnetic fields is a circular polarized magnetic field.
