Magnetic Field Modeling with a Set of Electrical Coils

Christoph Juchem¹, Terrence W. Nixon¹, Scott McIntyre¹, Douglas L. Rothman¹, Robin A. de Graaf¹

The theoretical and experimental generation of linear magnetic field gradients as well as more complex magnetic field distributions (e.g. X2-Y2, Z2, Z2X) with a set of 24 circular, localized coils is presented. Gradients as being generated with the multi-coil approach allowed radial imaging of a mouse head. The multi-coil approach allows a flexible trade-off between accuracy and strength of the generated fields. Furthermore, the parameters are readily optimized for the specific object and volume-of-interest under investigation.
