System and method for MRI tagging using spatial modulation of magnetization
Lead Inventors: Ed Xuekui WuA method of inducing tag lines in an MRI image which allows adjustment of tag line width and spacing is described. This method uses magnetic resonance imaging by spatial modulation of magnetization to establish a frame of reference in the form of tag lines on the resulting image.The method of inducing tag lines in an MRI image involves determining a desired tag line width. A gradient field is applied to the specimen to be imaged. Then a modulated RF pulse train is applied to the specimen being imaged before an image acquisition operation is performed.The method avoids a non-uniform gradient which causes aliasing. Various parameter of a SINC modulating function, such as main lobe bandwidth can be selected.
