A new concept in high-performance MR gradient coil design is presented which we have called the Modular Gradient Coil (MGC). This novel design approach results in an actively shielded whole-body gradient coil containing multiple and independent elements, integrated onto a single former, for generating gradient fields along each of the three axes (x, y, and z). These elements can be energized in a number of configurations, using a single gradient power supply unit (PSU), to generate a whole range of gradient performance levels. The design criteria for the MGC also include a requirement to prohibit peripheral nerve stimulation in all of its modes of operation. This requirement is achieved, while simultaneously providing high performance, by specifying different volumes of gradient linearity for each of the operating modes. Magn Reson Med 42:561-570, 1999.
本文提出了一种高性能磁共振梯度线圈设计的新概念，我们称之为模块化梯度线圈（MGC）。这种新颖的设计方法产生了一种有源屏蔽的全身梯度线圈，它包含多个独立元件，集成在单个骨架上，用于沿三个轴（x、y和z）中的每一个产生梯度场。这些元件可以使用单个梯度电源单元（PSU）以多种配置通电，以产生一系列梯度性能水平。MGC的设计标准还包括在其所有操作模式下禁止周围神经刺激的要求。通过为每种操作模式指定不同的梯度线性体积，在提供高性能的同时实现了这一要求。《磁共振医学》42:561 - 570，1999年。
