ABSTRACT:
The present invention relates to antennas for nuclear magnetic resonance imaging devices. The antenna (10) of the invention essentially is formed of two support plates (11, 12) made of electrically insulating material. Spacers (13) hold the two plates at a fixed distance apart in two parallel planes, and releasably fixing at least one of the two plates (11) to the spacer means (13). At least first and second turns (17, 18) of electrically conductive material are fixed on respective first faces (15, 16) of the two plates in order to form two current loops substantially centered on a common axis (100) perpendicular to the faces with capacitive coupling together of the ends of each current loop. The invention is applicable to scanners, in particular for scanning the human brain.
