An apparatus capable of high precision (< 1 ppb)
measurements of magnetic susceptibility has been
developed with broad potential in the characterization
of materials for MR instrumentation. Measurements of
3D-printed materials relevant to RF coil construction
have been performed. For example, 3D-printed ultem
differs in susceptibility from water, despite pure
ultems excellent match. Poly(methyl methacrylate) and
polycarbonate-based 3D-printed materials offer
alternatives which closely match waters magnetic
susceptibility.
