New approaches and pipelines for phantom creation as well as novel approaches to improving safety

		370-09-065. Towards a Polyacrylamide-Based Modular Phantom for Interventional MR: Realistic Tissue Properties and Thermal Stability Florian Kehrein, Qizhe Xu, Lars Fäßler, Daniel Schäfer, Nga Ly-Hartig, Lothar Schad, Frank Zoellner Medical Faculty Mannheim, Heidelberg University, Mannheim, Germany Impact: Polyacrylamide-based phantoms offer tunable relaxation times and tissue-like mechanics, enabling realistic MR thermometry, needle tracking, and ablation validation. Their thermal stability and adaptability form a robust foundation for modular organ-specific phantom development.
		370-09-066. Characterization of a high-resolution 3D-printed MRI phantom with realistic tissue anatomy Manoe Meunier, Jason Stockmann, Lawrence Wald, Thomas Allmendinger, Ido Bitan, Reut Reina, Stefan Popescu, Bastien Guerin Athinoula A. Martinos Center for Biomedical Imaging, Massachusetts General Hospital and Harvard Medical School, Charlestown, United States of America Impact: We characterize an MRI head phantom 3D-printed following an approach developed by Siemens and Stratasys, yielding detailed depiction of the anatomy. This innovation is expected to reduce the need for human subjects during the development and testing of MRI methods.
		370-09-067. Small-Bore, Big Fruits: End to end generation pipeline for 3D-printed phantoms with hidden micro-manifolds in Low-Field MRI Marcel Ochsendorf, Emilia Yin-Großmann, Kostiantyn Lavronenko, Volkmar Schulz Fraunhofer MEVIS, Bremen, Germany Impact: This automated pipeline makes phantom production for low-field MRI systems available to researchers without fabrication expertise by enabling them anatomically-accurate phantoms. The workflow is standardized, makes it possible to reproduce testing and quality assurance in open-source low-field MRI.
		370-09-068. Neural network models for real time monitoring of peripheral nerve stimulation (PNS) Arthur Poure, Valerie Klein, Coursey Sean, Mathias Davids, Lawrence Wald, Bastien Guerin Athinoula A. Martinos Center for Biomedical Imaging, Massachusetts General Hospital and Harvard Medical School, Charlestown, United States of America Impact: We train a CNN able to predict PNS for arbitrary gradient waveforms in 34 microseconds with less than <4% error and little overfitting, thus allowing utilization of gradients at peak performance while ensuring patient comfort and safety.
		370-09-069. Mind the Magnet! Learning MRI Safety Through Virtual Reality Marcus Meneses, Justine Wilson, Keith Widmeier, Amirreza Manteghinejad, Jennifer Lorenzi, Goerge Englehardt, Lorenna Vidal Children's Hospital of Philadelphia, Philadelphia, United States of America Impact: Virtual Reality-based simulation enhances MRI safety education, improving staff engagement and protocol adherence. This approach supports training and may reduce safety incidents related to inadequate metal screening, with potential for scalable staff education across many departments.
		370-09-070. Reducing RF-Induced Heating of DBS Implants in 3 T MRI Through Dual-Role Receive Array Technology Zhonghao Zhang, Ming Lu, Xiao Wang, Yuankai Huo, Xinqiang Yan Vanderbilt University, Nashville, United States of America Impact: The dual-role coil demonstrated excellent performance in controlling the transmit field and reducing heat generation at DBS implants, offering a promising solution for safer MRI in DBS patients.
		370-09-071. Evaluation of Implant-Induced SAR in Low-Field MRI (B0 = 50 mT) Using Representative Geometries Ariane Ernst, Lukas Winter, Umberto Zanovello, Frank Seifert Physikalisch-Technische Bundesanstalt (PTB), Braunschweig and Berlin, Berlin, Germany Impact: Electromagnetic simulations of a conservative U-shaped and a representative J-shaped conductive implant at 2 MHz (~0.05 T) show substantially lower absolute SAR_1g than at 3 T, providing quantitative reference scenarios for evaluating implant safety in low-field MRI.
		370-09-072. Implant Fracture Width Impacts RF Power Deposition in Biodegradable Orthopedic Screws Mostafa Berangi, Shahriar Shalikar, Thoralf Niendorf Max Delbrück Ctr for Molecular Med. in the Helmholtz, Germany Impact: This study reveals how fracture width in biodegradable orthopedic screws alters MRI-induced energy absorption. The results improve understanding of radiofrequency safety during implant degradation and guide the development of safer MRI protocols and future biodegradable implant designs.
		370-09-073. In-Vivo Assessment of Implant Displacement by Magnetically-induced Force in MRI Mona Shehada, Kareem Shehada, Hebah Mansour, Emile Ramez Shehada University of California, Irvine, United States of America Impact: This study provides benchmark data needed to prove safety of the magnetically induced force of subcutaneous implants, especially in the case where the force exceeds the weight of the device, without needing an extensive safety analysis while ensuring patient safety.
