SYSTEM AND METHOD FOR AN EDDY-CURRENT FIELD COMPENSATION IN MAGNETIC RESONANCE IMAGING

摘要

A method and system for acquiring a calibrated eddy-current field model in magnetic resonance imaging (MRI) are provided. The method may include one or more of the following operations. An eddy-current field model transformed by Laplace transformation may be obtained (501). Data of an eddy-current field may be obtained (502). The data of the eddy-current field may be processed (503). A calibrated eddy-current field model may be acquired (505). In addition, the calibrated eddy-current field model may be used to compensate an eddy-current field. According to the method and system, an accurate initial parameter for the eddy-current field model is obtained. With the initial parameter, the accuracy and efficiency of the compensation of the eddy-current field can be improved.
