A magnetron surface coil was developed for rodent MRI at 11.7 T. The prototype performance was Ql6.5=Qu, and, the noise figure was 1.6. Phantom images were acquired with the magnetron coil to prove its feasibility. A circular coil was also used to acquire phantom images for comparison purposes. A SNR roll-off comparison was computed and showed an improvement of the magnetron coil over the circular one. Image SNR values were also calculated showing a 28.14% improvement of our coil over the circular coil. These results demonstrate the versatility and feasibility of the magnetron design to be used at UHF MRI.
