| 摘要 |
A magnet system for nuclear spin resonance spectroscopy, in particular for in-vivo spectroscopy and tomography on a limb or a shoulder of a human body (partial-body tomography) comprising a superconductive magnet coil arrangement having coil sets (2a, 3a; 2b, 3b) arranged at an axial spacing one from the other, for generating a static homogeneous magnetic field in an examination volume, and further a coil frame (6) carrying the coil sets and a cryostat intended for cooling the windings, is characterized by the fact that the windings are rigidly interconnected by the coil frame at low temperature and that there is provided a transverse room-temperature access (50) to the examination volume which extends over approximately 180 DEG in circumferential direction, related to the axis (4) of the magnet coil arrangement. This enables examinations to be carried out at ease.
