ABSTRACT:
A two coil system is described which produces a linear gradient field inside and an arbitrarily low field outside the two coil set. By eliminating the field outside the gradient coils, interaction between the gradient coils and external structure can be eliminated. A reduction in eddy current effects of greater than a factor 100 are readily obtained. Two coils are required for each gradient axis instead of one so that some increase in power supply capability may be required.
