Abstract:
A transmission antenna for magnetic resonance applications has a birdcage-like structure that includes antenna rods proceeding between first and second terminating elements respectively located at opposite ends of the antenna rods. A detuning circuit is located at the second terminating element. Either the second terminating element is formed as a completely continuous short circuit ring and the detuning circuit is arranged between the ends of the antenna rods and the second terminating element, or the second terminating element has a number of ferrule segments, between which the detuning circuit is arranged. The second terminating element has a larger cross-section than a the first terminating element.
