设计和构建头部插入梯度线圈,与身体梯度结合使用以实现卓越的成像。使用边界元法求解任意表面上的梯度线圈导线图案,使我们能够将工程变更直接纳入梯度线圈的电磁设计中。改进的线型设计与稳健的制造技术和新颖的冷却方法相结合。成品线圈在所有三个轴上的效率均为 0.15 mT/m/A,并且允许成像区域延伸到整个头部和颈部上部。从工程角度来看,使电磁设计适应必要的变化的能力可以带来卓越的线圈性能。
To design and build a head insert gradient coil to use in conjunction with body gradients for superior imaging. The use of the Boundary Element Method to solve for a gradient coil wire pattern on an arbitrary surface has allowed us to incorporate engineering changes into the electromagnetic design of a gradient coil directly. Improved wire pattern design has been combined with robust manufacturing techniques and novel cooling methods. The finished coil had an efficiency of 0.15 mT/m/A in all three axes and allowed the imaging region to extend across the entire head and upper part of the neck. The ability to adapt your electromagnetic design to necessary changes from an engineering perspective leads to superior coil performance.
