For monkey brain functional MR imaging, sufficient SNR is essential to reveal significant functional activities. Through a series of numerical simulation, we have demonstrated that under 7T environment, to image macaque brain whose size is much smaller than the natural resonate dimension of a dipole antenna, combining dipole and loop can feasibly provide considerably high SNR in both local cortical and deep brain regions. It is believed that such design will effectively benefit functional MRI over macaque with much enhanced signal quality.
