摘要

本文介绍了一种用于MRI的头部线圈的设计。线圈中的电流分布在多个耦合谐振器上，以在大体积上实现高灵敏度和场均匀性。这种耦合谐振线圈在各个方向上的均匀性都优于鞍形线圈。与鸟笼盘管相比，其中心附近和中心以下跨轴截面均匀性相似，中心以上跨轴截面均匀性更好。在矢状截面上，耦合谐振腔线圈比鸟笼线圈更均匀。

A multiloop coupled resonator coil design for MRI

The author describes the design of a head coil for use in MRI. The current in the coil is distributed over multiple coupled resonators to achieve both high sensitivity and field uniformity over a large volume. This coupled resonator coil had better uniformity than a saddle coil in all directions. Compared to a birdcage coil, it had similar uniformity in transaxial sections near and inferior to center, and better uniformity in transaxial sections superior to center. The coupled resonator coil was more uniform than the birdcage coil in sagittal sections.<>
