Claim Text:
1. A coil arrangement for a magnetic induction impedance measurement apparatus, the coil arrangement comprising: an excitation coil configured to generate a magnetic excitation field in an object; a detection coil configured to detect a magnetic response field generated in response to the magnetic excitation field inducing a current in the object; a shimming coil configured to generate a magnetic shimming field in the detection coil; and a control unit configured to adjust the arrangement of the excitation coil, the detection coil and the shimming coil such that the field strength of a net magnetic excitation field in the detection coil resulting from the magnetic excitation field and the magnetic shimming field substantially equals an average value of a field strength of the magnetic response field in the detection coil.
