Patent ID: 8742759

Claim:
A high-frequency coil for a magnetic resonance imaging device, the magnetic imaging device having a plurality of surface coils and a resonance frequency corresponding to a frequency of a magnetic resonance signal of a predetermined nucleus, the high-frequency coil comprising: an electromagnetic decoupling means for preventing electromagnetic coupling between adjacent surface coils of the plurality of surface coils, wherein a plurality of the surface coils are disposed at intervals along a first direction, wherein the electromagnetic decoupling means comprises a loop conductor, the loop conductor comprising a capacitor, wherein the loop conductor is disposed at such a position that the loop conductor is magnetically coupled to two adjacent surface coils of the plurality of surface coils and generates a magnetic flux in a direction for canceling a magnetic flux generated by one of the two adjacent surface coils and interlinking with the other surface coil, and the loop conductor does not contact the two adjacent surface coils, wherein the loop conductor is in a plane perpendicular to a plane of the two adjacent surface coils and is a loop having no crossovers, and wherein an inductance of the loop conductor and a value of the capacitor are tuned so that a sum of magnetic fluxes interlinking with the other surface coil is minimized, and a resonance frequency of the electromagnetic decoupling means is smaller than a resonance frequency of the high-frequency coil.
