A direct postprocessing method for correcting RF inhomogeneity in MR imaging is proposed. First, two images with different flip-angles of ψ and 2ψ are obtained. Next, the spatial distribution maps of the sensitivity of the surface coil and theB 1 field intensity are produced by employing those images. Finally, the correction of the MR image is achieved, dividing the original image by distribution maps of the coil sensitivity and theB 1 field intensity. The method was applied to image obtained… CONTINUE READING
