RF RF coil based on birdcage coil and dipole antenna for MRI

摘要

The present invention relates to an RF coil for magnetic resonance imaging capable of improving the sensitivity and homogeneity of a magnetic field (B1) by combining a cage-type coil and a dipole antenna. A cage-type coil unit 110 including a pair of end rings 111 and 112 arranged to be in such a manner, and a plurality of legs 113 connecting the end rings 111 and 112 to each other; and a dipole antenna unit 120 including a plurality of dipole antennas 121 and 122 disposed on a predetermined radius in parallel with the central axis (Z axis) of the cage-type coil unit 110, wherein the dipole antenna unit Reference numeral 120 indicates that at least some sections are arranged within the range of the vertical height section h of the cage-type coil unit 110 .
