我们提出了一种设计用于脑成像的正交体积线圈，用于在3T的立体定向框架内固定在狮身人面像位置(面朝下)的猕猴，其中猴子的位置和框架的存在排除了使用现有线圈的可能性。要求包括能够在不干扰猴子在框架中的位置的情况下定位和移除线圈。马鞍形线圈和螺线管组合在一个改进的圆柱形形成器上，并以正交方式连接，在整个大脑中产生一个均匀的圆极化磁场。为了让马鞍圈的线圈包住耳柱，通过将销钉和插座触点嵌入前者的单独部分，使部分拆卸和重新组装变得容易。线圈设计包括模拟线圈的电磁场，线圈包含一个猴子头部的3D模型。由此产生的线圈在整个大脑中产生了足够的同质性和信噪比。
We present a quadrature volume coil designed for brain imaging of a macaque monkey fixed in a sphinx position (facing down the bore) within a stereotactic frame at 3 T, where the position of the monkey and presence of the frame preclude use of existing coils. Requirements include the ability to position and remove the coil without disturbing the position of the monkey in the frame. A saddle coil and a solenoid were combined on a modified cylindrical former and connected in quadrature as to produce a homogeneous circularly polarized field throughout the brain. To allow the loops of the saddle coil to encompass the ear posts, partial disassembly and reassembly were facilitated by embedding pin and socket contacts into separate pieces of the former. Coil design included simulation of the electromagnetic fields for the coil containing a 3D model of a monkey’s head. The resulting coil produced adequate homogeneity and signal-to-noise ratio throughout the brain.
