1. Apparatus for minimally invasively measuring concentrations of constituents contained within a biological tissue structure, the apparatus comprising:

  • a microwave energy source arranged to generate a range of microwave frequencies;

    a first antenna coupled to the microwave energy source and arranged to transmit at least a portion of the microwave energy into the tissue structure;

    a second antenna arranged to receive at least a portion of the microwave energy transmitted through the tissue structure;

    a signal processor arranged to determine the resonant frequency of the received microwave energy; and

    a data processor arranged to provide an output of the concentration of constituents within the biological tissue structure according to the determined resonant frequency.
