Birdcage RF coil Questions and Answers in MRI

Generation of rotating B1 field (green arrow) by a birdcage coil. Sinusoidal current is applied sequentially to rungs 1-6, each of which generates a local field in directions shown. A phase shift of 360/6 = 60 between the successive rungs produces a resonantly rotating B1 field.
