Patent ID: 7816919

Claim:
A magnetic resonance apparatus gantry comprising: a hollow cylindrical static magnet housing having an opening which accommodates therein a hollow cylindrical static field magnet; a hollow cylindrical gradient magnet housing which accommodates therein a hollow cylindrical gradient magnetic field coil located inside said hollow static field magnet and of a shorter axial length than the static field magnet, the hollow cylindrical static and gradient magnet housings having approximately parallel axes; a support unit which at least partially supports the gradient magnet housing on the static magnet housing, said support unit including a first support member mounted on the static magnet housing, a second support member mounted on the gradient magnet housing and supported by the first support member, and an adjustment unit which is placed inside the static magnet housing in the axial direction and which is movable in a first circumferential direction of the opening of the static magnet housing that is transverse to the approximately parallel axes and configured to change the relative positional relationship between the first support member and the second support member, of the support unit, thereby adjusting a relative positional relationship between the static magnet housing and the gradient magnet housing in a second transverse direction with respect to the approximately parallel axes.
