| Abstract | Introduction: The clinical implementation of high field MRI systems has introduced new challenges for body imaging with respect to B1 field nonuniformities, which can result in the generation of standing waves and signal loss particularly in abdominal imaging. Several approaches have been proposed to achieve a more homogeneous excitation and to avoid a degradation of image quality at higher magnetic fields, e.g. the use of RF cushions [1-2]. The recent development of parallel RF transmission techniques allows for independent adjustment of RF transmission signals enabling the concept of RF shimming [3-7]. In this study multi-source RF transmission with patient-adaptive RF shimming was evaluated for MR imaging of the liver at 3.0 Tesla. |
