Exact knowledge on the magnetic fields used in tomographic imaging systems is important for accurate sequenceplanning and model-based image reconstruction in existing devices. It is common to measure the magnetic fieldson a small subset of points and use spherical harmonics to approximate the fields inside a spherical region. However, most scanner bores could be better filled using a cylindrical or ellipsoidal region. In this work, we present the application of ellipsoidal harmonics for efficient approximation of a typical magnetic field in magnetic particleimaging.
