A self-shielded gradient adapted to be disposed within a main magnet field
of an MRI scanner includes a gradient coil having a shield current
distribution J.sub.s based on current density components .phi..sub.n on a
gradient surface where.times..times..times..PHI. ##EQU00001## The
current distribution is a predetermined value within a volume defined by
a periphery of the gradient coil. The current distribution is
substantially zero outside the periphery of the gradient coil. According
to a method of producing a self-shielded gradient, a shield current
distribution J.sub.s is determined based on current density components
.phi..sub.n on a gradient surface where.times..times..times..PHI.
##EQU00002## by using an optimization technique, and a gradient coil is
constructed according to the shield current distribution. The current
distribution is a predetermined value within a volume defined by a
periphery of the gradient coil. The current distribution is substantially
zero outside the periphery of the gradient coil.
