MULTI-CHANNEL RADIO TEMPERATURE RECORDER Russian patent published in 2007 - IPC G01R29/08 A61B6/02 

FIELD: radio engineering, possible use for measuring radio-thermal radiation of bodies, in particular, in medicine, for measuring temperature field of internal tissues of a human.

SUBSTANCE: multi-channel radio temperature recorder contains N antennas, connected to N UHF-switches, an additional UHF-switch, N temperature sensors, circulator, thermostat, matched load in thermal contact with thermostat which load is connected to circulator, output of which is connected to input of radiometric receiver. Noise generator and radiometric receiver are in thermal contact with thermostat, temperature sensors are in thermal contact with antennas and are connected to inputs of multi-channel temperature meter, output of which is connected to first input of controller. Outputs of N UHF-switches are connected to first input of circulator, controlling inputs of UHF-switches are connected to outputs of controller, matched load is connected to second input of circulator. Noise generator is connected to input of additional UHF-switch, output of which is connected to second input of circulator. Output of radiometric receiver is connected to input of analog-digital converter, output of which is connected to second input of controller, registration and indication block is connected to controller.

EFFECT: possible examination of temperature fields in the human body and also of dynamic changes of these fields, which occur under various influences and as a result of diseases.
