We construct an agar phantom to examine the SNR variation as the coil plane rotates from 0° to 90°, respect to B0. Our local pituitary coil has improved SNR with a factor, ranged from 3.3 to 4.2, compared to the commercial Siemens head coil as long as the surgical positioning of the coil to be within 0° and 70° with respect to the B0 field.
