By doping epoxide-resins with paramagnetic substances,
solid materials with widely adjustable magnetic
susceptibility can be produced. With this method, we
built an MR phantom whose susceptibility is matched to
air (including the liquid filling). It has the unique
properties of not affecting the magnetic field
homogeneity, neither internally nor externally, turning
it into a versatile tool for sequence development and
quality assurance in MR imaging and spectroscopy.
Furthermore, the excellent mechanical properties of this
material allow the construction of NMR equipment and
consumables that are invisible within the magnetic
field.
