Advancing dental surgical training with biomimetic lattice reinforcement in polyjet-printed models

Gunpreet Oberoi, Erik Kornfellner, Markus Königshofer, Bernhard Rosenauer et autres

BACKGROUND/ PURPOSE: Realistic soft-tissue behaviour is essential for surgical training, yet most additively manufactured models remain mechanically homogeneous. The purpose of this study was to investigate whether embedding biomimetic lattice architectures within standard PolyJet elastomers can improve the haptic and biomechanical realism …

Making solid polymers MR-visible: MR-characterization of micro-sphere modified resins for MR-phantoms and MR-guided radiation therapy

Andreas Berg, Paul Pery, Markus Ortner, Ewald Unger et autres

Motivation: Solid polymers could be very useful for MRI Quality-Control using stable-in-time phantoms, however, not being MR-visible due to short T2-relaxation-time. The invisibility represents also a severe problem in MR-guided radiation-therapy dose-planning and attenuation-correction in MR-PET scanners. Goal(s): Can the manufacturing-process be …
