Transcranial MRgFUS has been successfully used to treat a variety of neurodegenerative diseases. However, body coil brain image quality is poor, and a low-signal band artifact may occur in some regions due to RF wave reflections. Further, acoustic coil transparency has not been addressed extensively to date. In this work, we simulate a 10-channel coil design that can significantly increase the SNR by a factor of 20 over the body coil and thus indirectly improve the signal at the region of interests. Acoustic simulations/experiments exhibit transparency of the FUS-Flex coil as high as 97% at 650 kHz.
