Claim One:
1. A method of magnetic resonance comprising: disposing a plurality of fiducial markers on at least one of a subject and a medical accessory, the fiducial markers including dipoles having a first resonance frequency; disposing a subject in an imaging region of a main magnetic field; exciting magnetic resonance in dipoles of the fiducial markers and dipoles at least a portion of the subject concurrently with at least one radio frequency pulse, the dipoles of the subject having a second resonance frequency; spatially encoding the magnetic resonance with magnetic field gradients which spread the first and second resonance frequencies over spatially dependent first and second frequency spectra, the first and second spectra being separated from each other; receiving magnetic resonance signals from resonating dipoles of the subject and the fiducial markers; separating the magnetic resonance signals based on frequency spectra; reconstructing an image representation of the fiducial markers from the first spectra resonance signals; and, reconstructing an image representation of the at least a portion of the subject from the second spectra resonance signals.
