Solving a Sparse-Boundary Dirichlet Problem for Efficient Magnetic Field Mapping in MRI-Guided Radiotherapy Koen Vat, Teodor Stanescu UMC Utrecht, Utrecht, Netherlands Impact: Our computationally efficient BVP methodology accurately characterizes magnetic fields from sparse boundary data. This drastically reduces simulation resources , streamlining the design, optimization, and safety assessment of complex MRgRT systems.
		470-06-120. DTDM Coil Designer: An Open-Source Circuit Design Helper for Double-Tuned/Double-Matched Multinuclear RF Coil Chenhao Sun, Yonghyun Ha, Steven Wright, Gigi Galiana, R. Todd Constable Yale University, New Haven, United States of America Impact: As a critical component of multinuclear MRI systems, double-tuned RF coils and baluns are often challenging to construct. To streamline the designing process of matching networks for such double-resonant coils, an open-source circuit design helper is presented in this work.
		470-06-121. Retuning Flexible Coil’s Resonance Frequency Folk Narongrit, Joseph Rispoli Purdue University, West Lafayette, United States of America Impact: The frequency retuning system allows in-bore resonance frequency retuning for flexible MRI coils without ferromagnetic components. It facilitates multi-nuclear applications and improving coil performance in high-field MRI environments.
		470-06-122. Reconfigurable and smart metamaterials – new degrees of freedom in MRI Dennis Philipp, Johannes Mueller, Marc-Oliver Becker, Matthias Günther University of Bremen, Bremen, Germany Impact: Reconfigurable metamaterials allow for on-demand RF field shaping during and/or between acquisitions and, thus, introduce new degrees of freedom into MRI. The potential advantages are, e.g., tailored local and spatio-temporal SNR enhancement for manifold applications or imaging speed up.
		470-06-123. Toward Device Testing at 0.55 T: Tissue-Equivalent Media Assessment for Lead Heating Jessica Martinez, Ye Tian, Krishna Nayak, Kathryn Keenan National Institute of Standards and Technology, Boulder, United States of America Impact: Tissue-equivalent media for low-field implant SAR and thermal testing at 0.55 T have been validated through this study for various lead lengths. ASTM electrical properties show different SAR magnitudes compared to muscle-matched properties, with consistent distribution patterns across lead lengths.
