“LEE Imaging Ukraine” provides the service of ramp up and shim of 1.5T GE CXK4 magnets. Shimming the magnets is required for optimizing and unification of the magnetic fields.

Moving the magnet or presence of any ferromagnetic objects may cause the magnetic field distortion and will require the shimming procedure to unify the magnetic field.
