Design and application of a multimodality-compatible 1Tx/6Rx RF coil for monkey brain MRI at 7T

•A tight-fitting helmet-shape receive array with a single transmit loop for anesthetized macaque brain MRI at 7T was fabricated with four openings constructed to accommodate multimodal neuroimaging and neurostimulation devices.•The coil provides satisfactory transmit efficiency / homogeneity, signal coverage and SNR over the macaque brain.•Promising results obtained by combining fMRI with infrared neural stimulation, focused ultrasound stimulation, or transcranial direct current stimulation.•This pilot study reveals the opportunity for brain investigation at multiple spatiotemporal scales, which may advance our understanding in dynamic brain networks.
