Abstract
A surface coil assembly consisting of two interleaved coplanar resonators that are intrinsically decoupled from each other is described for imaging at 1.5 T. Vector reception fields on-axis at 3 cm depth are orthogonal and of equal magnitude. Both components of magnetization were received and combined resulting in a 2 1/2 improvement in signal-to-noise for temporomandibular joint images.
摘要
描述了一种表面线圈组件，其由两个相互内在解耦的交错共面谐振器组成，用于1.5T成像。在3cm深度处轴上的矢量接收场是正交的且大小相等。接收并合并了磁化的两个分量，从而使颞下颌关节图像的信噪比提高了2.5倍。
