ABSTRACT:
In a magnetic resonance scanner, a main magnet system (10) is wound to generate a longitudinally directed main magnetic field (B0) at least in a scanning region (20). The main magnet system includes a central magnet winding region (30) wound layer-by-layer disposed between outer magnet winding regions (32, 34). A longitudinal magnetic field gradient system (12, 12′) includes a central gradient winding region (40, 40′, 42, 42′) wound to generate a main longitudinally directed magnetic field gradient disposed between outer gradient winding regions (44, 46) wound to generate a compensatory longitudinally directed magnetic field gradient having opposite polarity from the main longitudinally directed magnetic field gradient. The outer gradient winding regions are arranged to substantially null mutual inductance between the outer magnet winding regions (32, 34) and the longitudinal magnetic field gradient system (12, 12′).
