Image-Guided Radio-Frequency Gain Calibration for High-Field MRI
High-field (≥ 3T) MRI provides a means to increase the signal-to-noise ratio, due to its higher tissue magnetization compared with 1.5T. However, both the static magnetic field (B(0)) and the transmit radio-frequency (RF) field (B(1)(+)) inhomogeneities are comparatively higher than those at 1.5T. T...
