title: Modular gradient coil: A new concept in high-performance whole-body gradient coil design.
abstract: 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.
