This work describes the design of an open access 10-channel brain RF coil for magnetic resonance guided high intensity focused ultrasound. The coil was built to be compatible with a head stereotactic device and waterproof for use in a water tank. This coil uses capacitive decoupling of adjacent loops. The coil is evaluated for SNR performance, temperature imaging performance, and a comparison of anatomy scans. The coil was found to give better SNR over the body coil. This SNR increase translates to better anatomy imaging and temperature measurements.
