Development of a double resonant fluorine-19 and proton coil for low-field MRI experiments

Motivation: Our project aims to refine MRI technology for a specific clinical purpose, focusing on a double-resonant coil design. This innovation bridges knowledge gaps and enhances diagnostic precision. Goal(s): Our goal during the current semester is to create a double-resonant coil for MRI experiments on fluorine and protons. Achieving this involves circuit design and hardware construction. Approach: Our approach includes capacitor and inductor integration, two separate output channels, and the development of essential hardware for signal acquisition using a didactic low field MR system. Results: The design allows us to measure T1 and T2 relaxation times and enables us to perform imaging as well. Impact: With the coil we performed proof-of-principle fluorine and proton measurements in a didactic low MR-system. It can be used to investigate samples with 1H and 19F without moving the sample. The non-proton channel can be tuned to other x-nuclei frequencies.
