A magnetometer system for medical use comprises one or more induction coils for detecting a time varying magnetic field. Each coil has a maximum outer diameter of 10 cm or less, and a configuration such that the ratio of the coil's length to its outer diameter is 0.9 or more, and the ratio of the coil's inner diameter to its outer diameter is 0.6 or more. Each induction coil comprises a magnetic core. The magnetometer system further comprises a detection circuit coupled to each coil and configured to convert a current or voltage generated in the coil by a time varying magnetic field to an output signal for use to analyse the time varying magnetic field.

Sensor configuration in magnetometer for medical use

A method for allowing a first party and a second party to obtain shared secret information is provided. The method comprises the steps of: obtaining, by the first party, a sequence of values A=X+Nwhere X is a sequence of values and Nis a random sequence associated with the first party; obtaining, by the second party, a sequence of values B=X+Nwhere Nis a random sequence associated with the second party; performing, by the first and second parties, a data matching procedure to identify corresponding pairs of values,,, in respective sequences A and B that match, wherein sequences A and B are discrete-valued sequences equal to, derived from, or derived using, sequences A and B; wherein the shared secret information is equal to, or derived from, or derived using, the matching values in sequences A and B.

Secure communication

A medical magnetometercomprising one or more induction coilsfor detecting a time varying magnetic field of a region of a subject's body, such as the heart. Each coil has a maximum outer diameter of 4 to 7 cm, and a configuration such that the ratio of the coil's length to its outer diameter is at least 0.5, and the ratio of the coil's inner diameter to its outer diameter is 0.5 or less. Each induction coilis coupled to a respective detection circuit comprising a low impedance pre-amplifier, a low pass filter, a notch filterto remove line noise, and an averaging element. Each detection circuit produces an output signalfor use to analyze the time varying magnetic field of the region of the subject's body.
