B1 inhomogeneity increases as strength of magnetic field increases. Various methods to reduce the B1 inhomogeneity have been developed. However, B1 inhomogeneity still remains in some cases of abdominal imaging, and a more effective method is required. In this study, a B1-control loop is combined with a receive array coil by using PIN diodes for generating the B1-control loop during the RF transmit period. A 12-channel gB1-control receive array coilh was fabricated, and both its receive sensitivity and the effect of B1 homogenization were confirmed experimentally. The B1-control receive array coil can improve B1 inhomogeneity, while maintaining receive sensitivity.
