DEVICE FOR DIAGNOSING FUNCTIONAL STATE OF BRAIN Russian patent published in 2020 - IPC A61B5/00 

FIELD: medicine.

SUBSTANCE: invention relates to medical equipment. Device for diagnosing functional state of cerebrum comprises N groups of k antennas of different frequency bands arranged on surface of head, k×N+k microwave switches, k×N temperature sensors in thermal contact with antennas, multichannel temperature meter, k circulators, k thermostats, k noise generators, k matched loads, k radiometric receivers, a switch, an analogue-to-digital converter, a controller and a computer. Simultaneously, the instrument comprises electrodes for removing biopotentials, connected through galvanic isolation assemblies to biopotential amplifiers paths, which outputs are connected through multiplexer to input of additional analogue-to-digital converter, control input of multiplexer and output of additional analogue-to-digital converter are connected to controller, and N groups of k antennae are located on the head surface in the electrodes arrangement system for bio-potential removal "10–20 %".

EFFECT: invention provides a significant increase in the diagnostic effectiveness of the functional state of the brain, its pathologies and functional disorders.
