Abstract
For the determination of all linearly independent components of an Nth order gradient tensor of a magnetic field, at least 3+2N planar gradiometers of the Nth order are arranged on at least 3 non-parallel and non-orthogonal surfaces. As a result, three-dimensional coil structures are not necessary.
