最小电感设计技术显着降低了梯度线圈电感,最大限度地减少了梯度线圈存储的磁能。然而,这种技术设计的平面梯度线圈往往磁场线性度较差。通过缩放由该方法导出的电流密度函数的空间频率,可以在少量牺牲梯度线圈电感的情况下极大地改善平面梯度线圈的磁场线性度。已经发现平面梯度线圈的品质因数可以通过缩放空间频率来改善。
Gradient coil inductance has been remarkably reduced by the minimum‐inductance design technique, which minimizes the magnetic energy stored by the gradient coil. The planar gradient coil designed by this technique, however, often has poor magnetic field linearity. Scaling the spatial frequencies of the current density function derived by this method, the magnetic field linearity of the planar gradient coil can be greatly improved with a small sacrifice of gradient coil inductance. A figure of merit of the planar gradient coil has been found to be improved by scaling the spatial frequencies.
