Title:
RF COIL DEVICE AND RF SHIELD DEVICE FOR DIFFERENT MRI MODES
Document Type and Number:
Japanese Patent JP2022115899
Kind Code:
A
Abstract:
To provide an RF coil device for improving homogeneity of a B1 magnetic field.SOLUTION: An RF coil device 140 comprises a first coil 200 and a second coil 202. The first coil 200 and the second coil 202 are provided as birdcage coils. The first coil 200 and the second coil 202 are arranged with a common center axis 118. The first coil 200 and the second coil 202 have rungs 204 which are arranged non-parallel to the center axis 118 of the RF coil device 140. The first coil 200 has a coil structure 210 different from the coil structure 210 of the second coil 202, and the first coil 200 and the second coil 202 are switchable to be active for different modes of operation. The present invention further provides a magnetic resonance (MR) imaging system comprising the RF coil device 140 and/or such an RF shield device.SELECTED DRAWING: Figure 2
