Title:
IMAGE-ENHANCED METASURFACE DEVICE FOR DUAL-NUCLEAR MRI
Document Type and Number:
WIPO Patent Application WO/2022/170753
Kind Code:
A1
Abstract:
A dual-nuclear magnetic field enhancement device (30), comprising a first cylindrical magnetic field enhancer (810) and a second cylindrical magnetic field enhancer (820), wherein the first cylindrical magnetic field enhancer (810) encloses a first accommodating space (819), and the first cylindrical magnetic field enhancer (810) is used for enhancing nuclear magnetic signals of hydrogen proton nuclei of a detected part; the second cylindrical magnetic field enhancer (820) is arranged in the first accommodating space (819), the second cylindrical magnetic field enhancer (820) encloses a second accommodating space (829), the detected part can be accommodated in the second accommodating space (829), the second cylindrical magnetic field enhancer (820) is used for enhancing nuclear magnetic signals of non-hydrogen proton nuclei of the detected part, and the first accommodating space (819) is larger than the second accommodating space (829); and when accommodated in the second accommodating space (829), the detected part is also accommodated in the first accommodating space (819). The dual-nuclear magnetic field enhancement device (30) simultaneously enhances two signal fields of dual-nuclear MRI of the hydrogen proton nuclei and the non-hydrogen proton nuclei.
Compared with the prior art, the dual-nuclear magnetic field enhancement device (30) has a better magnetic field enhancement effect. When applied to an MRI system for imaging, the dual-nuclear magnetic field enhancement device (30) can assist the MRI system in obtaining images with a higher quality.
