Patent ID: 7683622

Claim:
A radio-frequency transmission arrangement configured for a magnetic resonance system, comprising: a first antenna device that generates a first portion of an RF total B1 field; at least one antenna insert that generates a second portion of the RF total B1field, said total B1 field being generated by said first antenna device and said at least one antenna insert operating simultaneously in combination therewith; said first antenna device and said at least one antenna insert being concentric relative to each other; and said first antenna device and said at least one antenna insert respectively being configured to generate said first and second portions of said total B1 field in N different field distribution modes; and said first antenna device being configured to generate said first portion of the total B1 field as a basic mode and said at least one antenna insert being configured to generate the second portion of the total B1 field in each of the remaining N−1 field distribution modes other than said basic mode of the first antenna device.
