FIELD: antennas.SUBSTANCE: invention can be used to generate a magnetic resonance image. Essence of the invention is that system forming magnetic resonance image contains reel assembly configured to emit in the zone of image generation and/or receive radio-frequency energy from it. Reel Assembly has the first surface, configured directable to the image formation zone, and contains at least one reel element. Reel Assembly additionally contains radio-frequency screen switchable between locking for radio frequency state and transparent for radio frequency state. At least one reel element is located between the first surface and the radio frequency screen. Switchable radio-frequency screen has at least two conducting elements. Radio-frequency screen has at least one radio-frequency switch configured for electrical connection of at least two conducting elements in locking state and disconnection of at least two conducting elements in the transparent state.EFFECT: technical result is reducing communication between antenna elements used to transmit radio-frequency energy.13 cl, 29 dwg |
