中文摘要： 高温超导射频线圈在提高磁共振图像信噪比方面的优越性已经得到证实，并已经逐步走向产业化。但是目前的研究大多局限于单通道线圈，无法解决图像信噪比与FOV之间的矛盾。对高温超导相控阵射频线圈的研究很少，研究仅限于YBCO薄膜，线圈的通道数也只有2个通道，相控阵线圈的优势基本发挥不出来。本项目将从这个角度出发展开研究工作，研究基于Bi2223超导线的相控阵射频线圈，研究目标是使线圈单元数达到临床上的常规铜导体相控阵线圈的规模，推动高温超导射频线圈技术的进步，为高温超导射频线圈能够更好的走向临床应用打下结实的基础。

英文摘要： The advantages of high temperature superconducting RF coils in SNR of MR image has been confirmed, and has been gradually industrialization. However, current research is mostly limited to the single-channel coil, which can not solve the contradiction between the image SNR and FOV. Research on phased array coil made of high-temperature superconductor is little, and the study is limited to the YBCO film and the number of coils are limited to two. The advantage of the phased array coil does not come out. From this point of view , this project is going to study the Bi2223 superconductor based phased array coil. The goal of this study is that the number of the coil unit reaches the number of the phased-array coil made of the conventional copper conductor on the clinical, and promote the progress of the technology of high temperature superconducting RF coil,and lay the foundation for the clinical application of high-temperature superconductor RF coil.
