Abstract

<div notation="docdba" type="abstract" xml:base="/api/emi/section/47a0c6fb-0dcd-42fe-bd2a-16c8661c68f0/image" xml:lang="en"><p>A method of magnetic resonance (MR) tomography imaging an object 1 comprises arranging the object in a static magnetic field, subjecting the object to at least one radiofrequency pulse and magnetic field gradients for creating spatially encoded MR signals, acquiring MR signals, and reconstructing an object image utilizing the spatial encoding of the MR signals, wherein, during the acquiring step, the MR signals are subjected to a locally specific frequency modulation by means of at least one spatially restricted, time-varying magnetic modulation field with a component parallel to the static magnetic field, and the step of reconstructing the object image further utilizes the frequency modulation for obtaining spatial information from the spatially encoded MR signals. An MR imaging device 100 includes an MR scanner 110 with a magnetic field modulation source device 114 for creating a spatially restricted, time-varying magnetic modulation field, a control device 120 and a reconstruction device 130 for reconstructing the object image by utilizing a frequency modulation of collected MR signals for obtaining spatial image information.</p></div>
