Abstract:
The present invention relates to a MR tracking method and device. More specifically, the present invention relates to a magnetic resonance tracking method and device, using a magnetic-susceptible object. A magnetic iso-surface induced by the object is selectively excited with a corresponding frequency offset; the magnetic iso-surface is then projected on three axes of a k-space, from which projections the spatial position of the object is calculated.
