ABSTRACT:
A method of determining the condition of a bulk tissue sample, by: positioning a bulk tissue sample between a pair of induction coils (or antennae); passing a spectrum of alternating current (or voltage) through a first of the induction coils (or antennae); measuring spectrum of alternating current (or voltage) produced in the second of the induction coils (or antennae); and comparing the phase shift between the spectrum of alternating currents (or voltages) in the first and second induction coils (or antennae), thereby determining the condition of the bulk tissue sample. An apparatus for determining the condition of a bulk tissue sample, having: a first induction coil (or antenna); a second induction coil (or antenna); an alternating current power supply connected to the first induction coil (or antenna), the alternating current power supply configured to generate a spectrum of currents (or voltage) in the first induction coil (or antenna); and a measurement system connected to the second induction coil (or antenna), wherein the measurement system is configured to measure a phase shift difference in the spectrum of currents (or voltages) between the first and second induction coils (or antennae) when the first and second induction coils (or antennae) are positioned on opposite sides of a tissue sample.
