Fig. 1: Field of view coverage in an homogeneous field with shifted spheres and ellipsoid.

Shown is the coverage of an cylindrical field of view (displayed as a green line) when using several shifted spheres (displayed as red dashed lines) and an ellipsoid (displayed as a blue dotted line) in the central x, z-plane of the permanent magnet B0-field presented by O'Reilly et al.51. The B0-field is indicated in the background.
