A transceive array for laryngeal imaging at 7T was constructed, consisting of 5 shielded loop coils and 3 passively fed dipoles. The array is physically flexible due to the absence of lumped elements in the loops and shows very high inter-element isolation (greater than -19 dB) without implementing decoupling circuits, even though the elements are closely packed. After RF shimming using the array, high resolution turbo spin-echo images were acquired from a healthy volunteer.
