SYSTEM FOR SIMULTANEOUS CONTROL AND EVALUATION OF THE DYNAMICS OF PHYSIOLOGICAL PROCESSES UNDER CONDITIONS OF HUMAN MAGNETIC RESONANCE TOMOGRAPHY Russian patent published in 2021 - IPC A61B5/205 

FIELD: medical technology.

SUBSTANCE: invention relates to medical technology. A system for simultaneous monitoring and evaluation of the dynamics of physiological processes in the conditions of magnetic resonance imaging is proposed, including a screened unit for recording physiological signals contained in a shielded room of a magnetic resonance tomograph, sensors of galvanic skin response, photoplethysmograms, chest recursion, abdominal recursion, and motor activity, subject's headphones, subject's microphone and magnetic resonance tomograph. The shielded physiological signal recording unit contains an electromagnetic interference filter, pressure sensors, a multichannel analog-to-digital converter, a microcontroller, a battery, an optical transceiver, a galvanic skin response sensor, photoplethysmograms are connected to a splitter that is connected to a sensor cable connected to an electromagnetic interference filter. The magnetic resonance tomograph is connected in series with a synchronization unit, with a unit for matching with a PC and a personal computer. The chest recursion sensor, the abdominal cavity recursion sensor and the movement activity sensor are pneumatically connected to the pressure sensors. The system contains an optical-electrical module connected to the subject's headphones and microphone, a synchronization unit and serially connected to an audio signal mixer connected to a personal computer and the experimenter's microphone.

EFFECT: suppression of electromagnetic interference.
