Technology

The presented technology introduces a novel double-resonant coil arrangement designed for Magnetic Resonance Tomography (MRT) systems and MR/NMR spectroscopy systems. This coil arrangement enables the simultaneous excitation and detection of nuclear resonances from both protons (1 H) and selected X nuclei, enhancing the capabilities of MR imaging.

Problem addressed

Traditional coil arrangements for MR imaging struggle with efficiently capturing signals from both protons and X nuclei, especially at high field strengths. Existing methods for dual-tuning coil arrangements often lead to challenges such as increased electrical losses, difficulty in tuning, and limited decoupling between resonances.

Solution

The disclosed technology addresses these challenges by presenting a double-resonant coil design capable of exciting and detecting signals from both 1 H and X nuclei without significant losses or tuning difficulties. By utilizing a closed conductor loop divided into segments with adaptable connection elements, this coil arrangement facilitates dipole mode excitation at the 1 H frequency and homogeneous power distribution at the X-nucleus frequency.

Benefits and Potential Use

The double-resonant coil technology offers significant potential for advancing MR imaging in various applications, including medical diagnostics and research. It allows for improved signal-to-noise ratios, enhanced image quality, and expanded capabilities for capturing metabolic activity and structural details of tissues. The technology can be seamlessly integrated into existing MRT systems and MR/NMR spectroscopy setups, offering researchers and clinicians a powerful tool for non-invasive imaging and analysis.

In conclusion, the innovative double-resonant coil technology represents a significant advancement in MR imaging, promising enhanced performance and expanded capabilities for medical diagnostics and research.
