Design and Implementation of an 8-Channel ¹H/19F RF Coil for 11.74 T MRI

Key Points

• To design an 8-channel RF coil for dual-band ¹H and ¹⁹F imaging at 11.74 T MRI.
• Designed an 8-channel RF coil with 4 channels for hydrogen and 4 channels for fluorine.
• Tuned and matched each coil element to its respective operating frequency.
• Evaluated resonant and impedance characteristics through bench measurements.
• Obtained phantom images to assess channel performances and multi-channel reconstruction capabilities.
• Successfully acquired stable images for both hydrogen and fluorine channels.
• Achieved signal-to-noise ratios of 22.27 for ¹H and 5.91 for ¹⁹F.
• Confirmed the potential for preclinical ¹⁹F MRI studies using the designed RF coil.
