CRYOGENICALLY COOLED SUPERCONDUCTOR RF HEAD COIL ARRAY AND HEAD ONLY MRI SYSTEM WITH SUPERCONDUCTING

摘要

A cryogenically-cooled superconducting RF head-coil array which may be used in whole-body MRI scanners and/or in dedicated, head-only MRI systems. A superconducting main magnet system for a head-dedicated MRI system is also provided, and a head-only MRI system may comprise such a superconducting main magnet and a cryogenically-cooled superconducting RF head-coil array. The superconducting main magnet comprises a first and a second set of coaxial coils wherein the coils of the second set have a greater inner radius than the coils of the first set.
