Method and testing device for the field - quality testing of a magnetic resonance - antenna arrangement, and magnet resonance system and magnetic resonance - antenna arrangement

摘要

It is a method for field - quality testing a a plurality of antenna elements (50) comprising a magnetic resonance - antenna arrangement (5) of a magnetic resonance system (1) described. In this case, for at least a portion of the individual antenna elements (50) in each case at a receiver unit, a noise signal (rs) and / or a by means of a transmitting antenna (4, 30a, 30b) in the respective antenna elements (50) supplied test signal (ts) is determined. The noise signals (rs) and / or test signals (ts), with regard to certain characteristic data (kd, km) is analyzed and on the basis of this, a quality condition (qz) of the magnetic resonance - antenna arrangement (5) is determined. In addition, a testing device (20) for carrying out such a process, a magnet resonance system (1) with such a testing device (20) as well as a for this purpose, particularly suitable magnetic resonance - antenna arrangement described.
