We propose that a transmit coil can be optimized for certain modes of operation. It is well-known that when the number of channels of a degenerate birdcage coil increases coupling between channels becomes a significant problem. The high total reflection when only one of its channels is used as a transmitter caused a small portion of the power delivered to the body. However, when it is properly designed, in some modes of operations such as circularly-polarized mode, the total reflection become negligibly small. In this work, we demonstrate this effect on various two-row degenerate birdcage-coils together with simulations and experiments.
