Abstract:
Gradient coil assemblies for horizontal magnetic resonance imaging systems (MRIs) and methods of their manufacture. Some embodiments may be used with open MRIs and can be used with an instrument placed in the gap of the MRI. In general, concentrations of conductors or radially oriented conductors may be moved away from the gap of the MRI so as to reduce eddy currents that may be induced in any instrument placed within the gap. Systems for directly cooling primary gradient and shield coils may be utilized and various coil supporting structures may be used to assist in coil alignment or to facilitate use of an instrument in the MRI gap.

Claim (Index 1):
A self-shielded gradient coil assembly for a horizontal open magnetic resonance imaging system (MRI) used in conjunction with an instrument, the open MRI having a longitudinal axis and a first magnet and a second magnet separated by a gap, the instrument being located within a portion of the gap, the gradient coil assembly comprising:\n a supporting structure having a first portion and a second portion, each supporting structure portion mounted inside of a respective first and second MRI magnet; a plurality of shielding coils disposed within each supporting structure portion; a plurality of primary gradient coils disposed within each supporting structure portion between the shielding coils and the longitudinal axis; and electrical connections between the primary gradient and shielding coils arranged so that the electrical connections are located a sufficient distance from the gap to reduce eddy currents induced in the instrument.
