An inductive sensing system (8) is for detecting bleeding (e.g. blood pools) in one or more regions of the body. The system comprises a resonator circuit (10) having at least one antenna (12) which is driven with an oscillatory drive signal to cause generation of electromagnetic signals for application to a body. The signals induce eddy currents in the body which generate secondary EM signals returned from the body. These interact with the resonator circuit by adding an additional component of inductance to the circuit. This inductance component varies depending upon the conductivity of the fluid in which the eddy current is induced. Blood has a different conductivity to other body fluids. The system is configured to detect presence of abnormal accumulations of blood based on the additional inductance component. The system generates a data output representative of the determination.

A method of passively detecting radiofrequency (RF) signals spontaneously emitted by a non-equilibrium population of electrons that are spin polarized by flowing through a chiral media during relaxation of the spin polarized electrons to equilibrium at a frequency corresponding to a Zeeman spin-flip energy of the spin polarized electrons under influence of a magnetic field (MF). The MF is applied to the chiral media for a predefined time period to shift a frequency and magnitude of the spontaneously emitted RF signals in line with Zeeman effect. The shifted emitted RF signals is passively detected and stored for medical use applications using a receiver antenna tuned to a resonant frequency of the shifted emitted RF signals.

An inductive sensing system (8) has a resonator circuit (10) with an antenna (12) for simultaneously applying electro-magnetic signals to a body and sensing secondary electromagnetic signals returned from the body. The system includes signal sensing means (30) which is configured to detect a measure indicative of an imaginary part of an additional inductance component added to the resonator circuit by the secondary electromagnetic signals but which does not measure the real part. In particular, the signal sensing means may be configured to detect a measure indicative of damping in the resonator circuit (e.g. a damping factor), and comprises no means for detecting any measure indicative of variations in a natural frequency of the resonator circuit.
