FIELD: medicine.SUBSTANCE: invention relates to medical equipment, namely to devices for carrying out magnetic resonance tomography. Magnetic resonance system, which includes system of magnetic resonance visualisation, contains, contains main magnet, unit of gradient coils, high-frequency unit and monitor for analysis of signals from electrodes. Monitor includes printed circuit board with sites for soldering and connector, connecting electrode leads with printed circuit board and including electric connecting outlets, upper lugs and lower lugs. Connector also includes two snapping brackets, gearing with locks in printed circuit board, preventing separation of connector and printed circuit board and rotation of connector around vertical axis relative to printed circuit board. Projection of one of the lugs comes into gear with cut in printed circuit board and is displaced aside between snapping brackets in such a way that snapping brackets are not able to come into gear with locks for snapping, if lug projection does not come into gear with cut. Monitor version includes monitor, used in zones with magnetic and HF fields and connecting electronic circuits for processing of ECG signals. In method of subject control in magnetic field magnetic resonance system is used, with control of subject's physiological being carried out by means of electrodes; vertical displacement, rocking and transverse rotation of connector are prevented, and information from electrodes to monitor is transmitted via leads.EFFECT: more reliable and stable connection of leads of electrodes with printed circuit board and prevention of incorrect connection of connector with printed circuit board are ensured.14 cl, 5 dwg |
