Magnetic-Resonance-Based Electrical Property Mapping Using Global Maxwell Tomography With an 8-Channel Head Coil at 7 Tesla: A Simulation Study

Ilias I. Giannakopoulos et al.

Summary: This study assessed the performance of Global Maxwell Tomography (GMT) with a realistic RF coil design, demonstrating reliable reconstruction of electrical properties in simulated head models. Despite errors in EP estimation, accurate prediction of RF transmit field and absorbed power was achieved, with potential future applications in patient-specific RF power deposition estimation for ultra-high-field MRI.

Optimization of MRI Gradient Coils With Explicit Peripheral Nerve Stimulation Constraints

Mathias Davids et al.

Summary: By incorporating PNS effects into the coil optimization process, researchers can identify design solutions that minimize PNS while satisfying engineering constraints. This allows for up to a 2-fold reduction in PNS propensity with moderate penalties in coil inductance and field linearity, potentially doubling the image encoding performance that can be safely used in humans. This framework may also be applicable in designing and operating magneto- and electro-stimulation devices.

Fast Fourier transform-volume integral: a smart approach for the electromagnetic design of complex systems in large fusion devices

P. Bettini et al.

Summary: The article proposes a volume integral equation method based on the fast Fourier transform for electromagnetic simulation of complex systems in large magnetic confinement fusion devices. This FFT-VI method significantly reduces the time and human effort required to adapt CAD input files to electromagnetic simulation models, and enables automatic and efficient mesh generation. The adoption of FFT allows for a substantial reduction in computation time and memory requirements, making simulations with millions of unknowns feasible.

Optimized cycle basis in volume integral formulations for large scale eddy-current problems

Dimitri Voltolina et al.

Summary: This paper presents a Volume Integral formulation for solving large scale eddy-current problems coupled with low-rank approximation techniques. By considering local and global cycles differently and based on cohomology theory, the bottleneck of the problem can be overcome. An improved, efficient, and robust algorithm for computing a base of global cycles is detailed in the paper.

Real-Time Numerical Dosimetry of Low-Frequency Electromagnetic Fields by Using Multipoles

Francois Tavernier et al.

Summary: The computation of the internal electric field induced in the human body by low-frequency power systems is time-consuming. However, a faster and more efficient method has been developed using a reduced basis and multipole approximation, allowing for nearly real-time calculation of the internal field. The results were validated against finite element method computation, showing significant improvements in computational efficiency and speed.

In silico assessment of collateral eddy current heating in biocompatible implants subjected to magnetic hyperthermia treatments

Irene Rubia-Rodriguez et al.

Summary: This study evaluates the impact of secondary magnetic fields generated by metallic prostheses on the safety and efficiency of magnetic hyperthermia treatments for localized tumors. It proposes using a combination of multi-criteria decision analysis and graphical representation of calculated data as an initial screening tool for preclinical risk assessment. By numerically solving the Maxwell equations and heat exchange problem, the study highlights the need to revise the current exclusion criterion for implant-bearing patients in magnetic hyperthermia procedures.
