Patent number: 10537265Abstract: A system includes a data receiver, a sinogram generator, a processor, a filter module, and an output module. The data receiver is configured to receive radial ordered magnetic resonance data. The sinogram generator is configured to generate a first sinogram corresponding to a view angle as a function of a readout direction for the magnetic resonance data. The processor is configured to generate an oscillogram having an angular frequency axis. The oscillogram corresponds to a Fourier transform of the first sinogram. The filter module is configured to selectively filter a peak in a projection formed along a selected axis of the oscillogram, the peak being related to an interference signal such as an RF interference. The selected axis is orthogonal to the angular frequency axis. The output module is configured to form a second sinogram corresponding to a transform of the filtered projection.Type: GrantFiled: March 31, 2011Date of Patent: January 21, 2020Assignee: Regents of the University of MinnesotaInventors: Curtis A. Corum, Djaudat S. Idiyatullin, Steen Moeller, Michael G. Garwood
