Parallel magnetic particle imaging: compressed sensing of field free line excitations

Oude Booijink, N.H.M. (2016) Parallel magnetic particle imaging: compressed sensing of field free line excitations.

Abstract:We developed a speed versus quality improvement of the currently most promising imaging modality that images superparamagnetic nanoparticles that are injected into a body: Magnetic Particle Imaging (MPI). We design a more informative hardware setup, that uses multiple receive channels similar to the setup in parallel Magnetic Resonance Imaging (MRI). To process the simulated data from these parallel coils, we use convex optimization reconstruction algorithms that can combine the extra information to find either the same image quality at shorter scan time, or improve image quality at the same scan time. To get the speed improvement, we decrease the number of projections in field free line MPI, so that Fourier space is undersampled. The idea for this was inspired by results from Magnetic Resonance Imaging, and the Fourier Slice Theorem. This motivated us to be the first to prove that the concept of parallel imaging can be applied to MPI.
