The "forward" method of an optimal gradient coil design provides a coil that has the minimal cost function value. It is shown in this study that the solution obtained by minimizing the cost function is directly dependent on the specified cost function and generally results in a deviation from the mo
## Abstract MRI gradient coil design is a type of nonlinear constrained optimization. A practical problem in transverse gradient coil design using the conjugate gradient descent (CGD) method is that wire elements move at different rates along orthogonal directions (__r, ฯ, z__), and tend to cross,
A distributed coil design is described which employs active force shielding to reduce acoustic noise. Both axial and transverse gradients employ sets of distributed pairs of coplanar closed-arc loops whose planes are normal to the static magnetic field direction. The resulting gradients are also par
## Abstract Designing gradient coils for permanent magnets requires modeling the interaction between the currents and the ferromagnetic material. We have developed and tested an iterative design approach based on the boundary element method. The power dissipated by the gradient coil is treated as a
