An eight-channel RF coil was developed for imaging the common marmoset at 9.4T. The coil was adjustable in width to accommodate different head sizes while maintaining high SNR, thereby facilitating the study of larger cohorts of animals. Tuning and matching of the coil did not require adjustment over the range of potential head sizes. EPI time series were acquired, showing minimal geometric distortion with a two-fold reduction factor. A two-fold reduction factor could be achieved in both the left-right and anterior-posterior directions.
