A 30 channel Rx array for 23Na MRI at 7 Tesla is compared with a reference Tx/Rx birdcage. Strong SNR improvement by the array technology is acknowledged and good B1 homogeneity could be found. Images were reconstructed using der adaptice combine algorithm which provides a near perfect channel combination.
