摘要：
A coil arrangement for a magnetic induction impedance measurement apparatus includes an excitation coil configured to generate a magnetic excitation field in an object, a shimming coil configured to generate a shimming field, and a detection coil configured to detect a magnetic response field generated in response to the magnetic excitation field inducing a current in the object. In order to enhance an accuracy of a determination of a parameter of an object, a value of a field strength of a net magnetic excitation field in the detection coil, being the sum of the excitation field and the shimming field, is approximately within a magnitude range of an average value of a field strength of the magnetic response field in the detection coil.
