| 摘要 |
A multi-channel RF transmitter arrangement in the form of, or comprising, a plurality RF antennas, antenna elements, coils or coil elements (11 to 16), for generating an RF field, especially for use in a magnetic resonance imaging (MRI) system for exciting nuclear magnetic resonances (NMR), and a method for generating such an RF field is disclosed. Furthermore, a multi-channel RF transmit system comprising a plurality of RF waveform generators (31, 32,...3n) and RF amplifiers (21, 22,...2n) for generating RF transmit signals for feeding such a multi-channel RF transmitter arrangement, especially for use as an RF excitation system in an MRI system is disclosed. |
