MULTIRESONANCE TRANSMIT/RECEIVE ANTENNA FOR MR-TOMOGRAM\GENERATION Russian patent published in 2017 - IPC G01R33/36 

FIELD: medicine.

SUBSTANCE: invention refers to a double or multiresonance radiofrequency (RF)/magnetic resonance (MR) transmitting and/or receiving antenna. Dual or multiresonance transmitting and/or receiving RF/MR-antenna consists of a coil and of at least one resonant circuit which is connected to the coil in series, at that, the antenna is inductively coupled to the transmitting and/or receiving RF/MR-channel via the inductive coupling device forming at least one loop or coil (L1, L2), which is sized and/or positioned relative to the antenna so that the resonant frequencies of the antenna are tuned to the Larmor frequencies of two or more nuclei of interest by means of the resulting magnetic flux between coils, and the impedance complies with the connected transmitting and/or receiving RF/MR-channel, wherein at least one loop or coil (L1, L2) is positioned so that it can be mechanically moved relative to antenna in order to adjust the magentic flux between the antenna and the inductive coupling device, at that the inductive coupling is broadband, and adjustment and compliance are applicable to both or all resonant frequencies.

EFFECT: invention provides simplification of adjustment and harmonization of double or multiresonance transmitting and/or receiving RF/MR-antenna.
