An Open-Source Software Toolbox for Rapid Radiofrequency Coil Design and Evaluation in MRI.
Article in Magnetic resonance in medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeImage quality and resolution in MRI are fundamentally constrained by the performance of radiofrequency (RF) coils used to excite the spins and receive the signal. Electromagnetic (EM) simulations are essential for optimizing coil performance. Existing tools are often slow, memory-intensive, and require expensive licenses. To address these limitations, we introduce a novel, comprehensive, open-source EM simulation tool for RF coil design in MRI. THEORY AND
methodsOur toolbox consists of four complementary software components: (1) a full-wave 3D EM solver based on the wire-surface-volume integral equation (WSVIE), where tensor decompositions reduce memory usage and accelerate simulations for fine body model resolutions; (2) a reduced-order model technique enabling patient-specific coil simulations in minutes; (3) a fully automatic circuit co-simulator for coil tuning, matching, decoupling, preamplifier decoupling, and detuning; and (4) a numerical EM basis generator that can be used to compute ultimate performance metrics. We demonstrated the toolbox with a series of simulations for different applications at 7 T MRI.
resultsOur proposed reduced-order model WSVIE solver was 70 times faster compared to a commercial solver for the simulation of a 31-channel 7 T head coil. Our co-simulator tuned, matched, and decoupled the array in 30 min, compared to a few days time of manual interactions needed with the commercial package. The average difference between the signal-to-noise ratio maps was less than 15%.
conclusionThe proposed open-source simulation framework enables fast, memory-friendly, accurate, and anatomy-specific RF coil array design, making it a powerful tool for RF coil engineering.
