ANTENNA SYSTEM FOR APPARATUSES OF MAGNETORESONANCE IMAGE AND NUCLEAR MAGNETORESONANCE APPARATUSES Russian patent published in 2001 - IPC

FIELD: magnetoresonance engineering. SUBSTANCE: the antenna system has the first and second electromagnetically coupled resonance circuits. The first circuit has the first inductance coil (16) producing the first vector of flux of the electromagnetic field. The second circuit has the second inductance coil (17) producing the second vector of flux of the electromagnetic field. The first vector of flux contains a component that is parallel to the second vector. The system of selector switches (18,19) is coupled to these first and second circuits. This system of selector switches has the first position for connection of the first circuit to the output of the microwave signal transmitter and for prevention of application of signal from the second circuit to the input of the receiver of the microwave signal and the second position providing for application of the microwave signal from the second circuit to the input of the signal receiver, and for disconnection of the first circuit from the output of the signal transmitter. EFFECT: produced a single antenna overlapping the object by its emittance, and antenna small dimensions with ability of various directivity. 35 cl, 11 dwg
