Motivation: MaRCoS is an open-source tool integrating hardware, firmware, and software for low-field MRI system control. But releases lacked user-friendly features, requiring technicians to handle automatable operations manually.
Goal(s): To simplify clinical workflows, we developed a device for RF coil impedance tuning and matching in systems controlled by MaRCoS.
Approach: Our approach involved designing a TM device using switchable capacitors and testing it in a real clinical environment on a portable 72 mT system.
Results: The auto-TM system, tested on 20 volunteers (40 protocols), significantly accelerated and improved workflow compared to manual methods, marking a substantial advancement in MRI system efficiency and usability.
Impact: The introduction of our automatic tuning and matching device eases low-field MRI systems controlled by MaRCoS. By simplifying clinical workflows and improving efficiency, this innovation enhances the user experience, simplifing the workflow under clinical environments.
