    • System and method of inductively measuring the bio-impedance of a conductive tissueThe present invention relates to a system (100) and method of inductively measuring the bio-impedance of a conductive tissue (106). Furthermore the invention relates to a computer program (115) for operating such a system (100). In order to provide a fast, simple and reliable adjustment technique for an inductively bio-impedance measuring system (100) with separate generator and sensor coils (101, 108; 117) a system (100) is suggested, the system (100) comprising a generator coil (101) adapted for generating a primary magnetic field, said primary magnetic field inducing an eddy current in the conductive tissue (106), a separate sensor coil (108; 117) adapted for sensing a secondary magnetic field, said secondary magnetic field being generated as a result of said eddy current, with the axis (109) of the sensor coil (108; 117) being orientated substantially perpendicular to the flux lines of the primary magnetic field (103), and a shimming coil (113; 120) adapted for generating a tertiary magnetic field in a way that in the sensor coil (108; 117) the primary magnetic field is cancelled out.
