CARDIOSYNCHRONIZER DEVICE FOR BUILDING MAGNETIC RESONANCE IMAGES Russian patent published in 1998 - IPC

FIELD: medical engineering. SUBSTANCE: device has signal shaper and signal receiver connected in information processing circuit through light-conducting cable. The signal shaper and signal receiver are designed as two separate units of which the former is fixed on the patient body and the latter is positioned beyond the operation zone of tomograph. Special features of the cardiosynchronizer imply that launching signal is sent through the light-conducting cable in the form of light pulse and autonomous low voltage power supply source with automatic switch switching on voltage supply under the action of permanent magnetic field is included into the structure of the signal shaper. EFFECT: high reliability of synchronization. 1 dwg
