The sensitivity gain available through high field in combination with multi-channel detectors allows a dramatic improvement in resolution for MRI of human brain. However, image intensity variations that result from non-uniformity of transmit and receive B1 fields compromise their interpretability. In this work, we present a simple method that allows for correction of these intensity variations by using a reference scan. The results are demonstrated for high-resolution T1-weighted imaging using a 24-channel detector array at 7 T.
