1. A magnetic induction tomographic apparatus for monitoring a multiphase fluid within an interior volume defined by a body, the apparatus comprising:
a a magnetic field generator adapted to generate a magnetic field within the interior volume defined by the body, the magnetic field temporally varying according to at least one frequency, thereby to apply the varying magnetic field to a multiphase fluid within the volume;
b a voltage detector adapted to measure an induced complex voltage which has been produced by electromagnetic induction from at least one phase of the multiphase fluid within the volume;
c a signal processor for determining, from the measured induced complex voltage, both an amplitude and a phase angle of the complex voltage, thereby respectively to provide amplitude data and phase angle data;
d a data processor for calculating, from the amplitude data and phase angle data, first output data from the amplitude data and second output data from the phase angle data, wherein the first output data is a function of the electrical permittivity and electrical conductivity of the at least one phase of the multiphase fluid and the second output data is a function of the electrical conductivity of the at least one phase of the multiphase fluid;
e an analyser for processing the first and second output data to generate analysed data representing at least one property of at least one electrically non-conductive phase in the multiphase fluid and at least one property of at least one electrically conductive phase in the multiphase fluid; and
f an imaging module adapted to process the analysed data to produce image data in a form representing the multiphase fluid within the volume across at least a portion of a cross-sectional area of the volume.
