A combination between a bilateral 2x4 channel T/R Arterial Spin Labeling (ASL) array and a 8 channel T/R head coil at 7 Tesla was developed. The achievable B1+ transmit efficiency of the ASL array is in the order of 0.8 μT/Volt and corresponding post-shim TX efficiency was calculated to be ~80% within the carotid arteries.
