摘要：
Methods and circuit arrangements for operating a multi-channel transmit / receive antenna device or arrangement, comprising a power monitoring unit, especially for use in a magnetic resonance imaging (MRI) system are disclosed. These methods and circuit arrangements are especially provided for ensuring that a specific absorption rate of a patient is not exceeded in the case in which antenna devices or arrangements are used which comprise a plurality of coils and / or coil segments which are independently supplied with RF transmit signals with different amplitudes and / or phases and / or waveforms and / or power levels. (Fig. 1)
