A medical device for the measurement of brain temperature data through the Abreu brain thermal tunnel (ABTT) is described. Brain temperature measurement is the key and universal indicator of both disease and health equally, and is the only vital sign that cannot be artificially changed by emotional states. Currently, brain temperature is difficult to measure. However, the present disclosure describes a device that readily locates the Abreu brain thermal tunnel, and is configured to provide a non-contact temperature reading of the brain. Embodiments of the disclosed device enable an individual to measure their own temperature and enable medical professionals to measure the temperature of others.

A measurement system is proposed for building a magnetic field map of an object. The system comprising: a light source arrangement for emitting a plurality of light beams, a respective light beam being configured to travel in the measurement system along a respective optical path; a plurality of measurement sensors sharing a first magneto-optical layer comprising at least a first Faraday material layer and a first light reflector for reflecting the plurality of light beams travelled through the first Faraday material layer in a first direction back to the first Faraday material layer in a second, opposite direction; one or more reference sensors; and one or more light detectors.

A system for positioning and maintaining a position of a reference sensor around a magnetoencephalography helmet. The system includes an arch comprising at least one fixing branch for fixing the arch to an MEG helmet, a support plate on which the branch is fixed, a sensor support post fixed to the support plate of the arch; and a locking component for fixing the reference sensor to the post in at least one position defining the position with respect to an MEG helmet.

An OPM sensor fastening system includes a support socket for positioning the sensor, the support socket having a base and a housing for accommodating a portion of the OPM sensor, and a locking part for locking the sensor in the support socket, the locking part having an open base suitable for accommodating the base of the socket, a housing for accommodating a portion of the OPM sensor, and a removable partition suitable for letting the OPM sensor pass. The locking part is configured to press-fittingly cooperate with the support socket so as to blockingly wedge the OPM sensor in the longitudinal position relative to the socket.

The invention provides a method and apparatus for acquisition and analysis of data that displays a linear relationship or can be transformed into a linearized relationship, such as electrophysiological signal data from sensors such as those suitable for EEG, MEG, ECG and the like. The method, which can be implemented in computer software, includes computing a cortical current flow vector field or a distribution of activity-indicating values for cortical locations according to an existing method of choice, determining, which currents are not inward-flowing, and defining a diagonal weighting matrix whose entries representing locations where currents are not inward-flowing are smaller compared to its other entries and re-calculating the cortical current flow vector according to the method of choice but incorporating the diagonal weighting matrix, or modifying the distribution of activity-indicating values, such that values representing locations where currents are not inward-flowing indicate smaller activity than before the modification. The outputs of the method can be stored in computer files for display on suitable monitors.
