Device for insertion into body tissue for examination by nuclear spin resonance tomography, e.g. medical implant/instrument, has diamagnetic material provided at least occasionally to compensate for paramagnetic material magnetic properties

摘要

The insertion device (31) consists at least partly of a paramagnetic material (32). A diamagnetic material (33) is provided at least occasionally to compensate for the magnetic properties of the paramagnetic material. The diamagnetic material can be fixed to the paramagnetic material. The diamagnetic material can be attached at least partly externally to the device.
