Magnetic-field modeling with surface currents: Physical and computational principles of bfieldtools
Antti J. Mäkinen, Rasmus Zetter, Joonas Iivanainen +3
Surface currents provide a general way to model static magnetic fields in source-free volumes. To facilitate the use of surface currents in magneto-quasistatic problems, we have im…
Evaluating the Performance of Ultra-Low-Field MRI for In-vivo 3D Current Density Imaging of the Human Head
Peter Hömmen, Antti J. Mäkinen, Alexander Hunold +5
Magnetic fields associated with currents flowing in tissue can be measured non-invasively by means of zero-field-encoded ultra-low-field magnetic resonance imaging (ULF MRI) enabli…
Automatic Spatial Calibration of Ultra-Low-Field MRI for High-Accuracy Hybrid MEG--MRI
Antti J. Mäkinen, Koos C. J. Zevenhoven, Risto J. Ilmoniemi
With a hybrid MEG--MRI device that uses the same sensors for both modalities, the co-registration of MRI and MEG data can be replaced by an automatic calibration step. Based on the…
