Document Type and Number:
Japanese Patent JPS61148310
Kind Code:
U
Abstract:
A high frequency antenna system for nuclear magnetic resonance tomography devices generates a substantially uniform magnetic high frequency field and receives high frequency signals, and includes two conductor members supplied with current of opposite polarity, the conductor members being of a selected length and extending along an imaginary cylinder parallel to the direction of the cylinder axis. Electrodes are provided at the end regions of the conductor members, the electrodes maintaining the electrical field generated at the ends of the current-supplied conductor members away from the examination chamber, and limiting the magnetic high-frequency field generated by the current-supplied conductor members substantially to the examination chamber between the electrodes.
