We introduced a customized setup for awake sitting macaque MRI in a 7T horizontal-bore human scanner. Considerations in the specialized design of monkey cage and head fixation device consisting of 1) monkey comfort in a Sphinx position, 2) stable head fixation, 3) easy mounting of the surface array for cortex imaging, and 4) easy presentation of visual stimuli. Our findings demonstrate that, in a well-trained awake monkey, with the increased contrast sensitivity and substantial gains in spatial resolution offered by ultra-high field MRI and a custom-made dense RF array, our setup is capable of achieving improved SNR and high time efficiency.
