Synopsis

Keywords: High-Field MRI, Magnets (B0), Cryogenics; Low-Cryogen; CompactSteps in the construction of an 8 metric ton, 7.0 T MRI scanner for imaging the brain are described. The system nearing completion uses only 12 liters of liquid helium and has outside dimensions comparable to a clinical whole-body 3.0 T scanner, with a similar footprint. As such, the new Compact 7.0 T system fits into any whole-body 3.0 T room, simplifying installation. The system is in the final stages of assembly.
