ABSTRACT:
A RF coil according to the invention is made up of an 8-shaped coil having a crossed conductive path, and an impedance adjustment coil that performs connection between crossing points of the conductive path. The crossing points of the conductive path are connected in parallel by the impedance adjustment coil and a floating capacitance between the crossing points of the conductive path. An impedance between the crossing points of the conductive path is increased, and a current that flows between the crossing points of the conductive path reduces in a Larmor frequency that is in proportion to the intensity of the magnetostatic field of an MRI apparatus. The RF coil according to the invention is made up of an 8-shaped coil having a crossed conductive path, an impedance adjustment coil that performs connection between the crossing points of the conductive path in parallel, and an impedance adjustment coil.
