Method and circuit arrangement for operating multi-channel transmit/receive antenna devices |
摘要 |
Methods and circuit arrangements for operating a multi-channel transmit/receive antenna device or arrangement, especially for use in a magnetic resonance imaging (MRI) system, are disclosed by which RF amplifiers can be used to their full peak power capability without running the risk that the RF amplifier is damaged due to excessive reflected power at its output. Furthermore by evaluating certain forward and reflected power signals patient safety is achieved with respect to monitoring the limits of the specific absorption rate.
