An HTS magnet for whole-body MRI.

Author(s) : BYRNE A. F., DAVIES F. J., RAYNOR C., et al.

Summary

The authors have successfully tested the first MRI electromagnet that uses HTS coils. The system comprises a C-shaped iron yoke and two pole pieces, each energized by a coil made from BSCCO-2223 tape, with a flux density of 0.2 T in the 46 cm patient gap. The coils were manufactured separately in Erlangen and Oxford, using conductor supplied by Vacuumschmelze and Nordic Superconductor Technologies respectively, as a stack of pancake coils 80 cm in diameter. The operating temperature of 20 K was maintained by a separate single stage Leybold RGS120T refrigerator for each coil.
