Zusammenfassung:In the context of the SPIRITS project a 3D-printed design of an assistance robot for interventional surgery under Magnetic Resonance Imaging (MRI) is developed1,2. It is of the outmost importance that the manufactured components do not affect the image quality3. Artefacts in imaging could be caused on one hand by eddy currents due to the numerous loops of the auxetic structure (Fig. 1), and on the other hand by the nickel-containing shape memory alloy NiTi consisting of approx. 50 % Ni, which is ferromagnetic in its elementary form3.
