Method for calibration of a magnetic resonance acquisition channel, calibration data determination device and magnetic resonance system

A calibration data determination processor for calibrating a magnetic resonance acquisition channel in a magnetic resonance system, comprising:

• a test signal initiation unit that causes a magnetic resonance antenna system of the magnetic resonance system to radiate a test signal;
• a test signal acquisition interface connected to said antenna system that receives, from said antenna system, the test signal detected by said antenna system, as a received test signal;
• a test signal analysis unit that automatically determines acquisition channel calibration data for said acquisition channel from said received test signal;
• and
• a memory in which said calibration data are stored in a form accessible for calibrating said acquisition channel using said acquisition channel calibration data.

A magnetic resonance system comprising:

• an antenna system that radiates RF signals into a subject and that receives magnetic resonance diagnostic signals resulting therefrom;
• an acquisition channel in which said magnetic resonance diagnostic signals are received from said antenna system;
• a control unit that operates said antenna system to radiate a test signal and, with said antenna system, to detect said test signal as a received test signal;
• a processor that automatically determining acquisition channel calibration data for said acquisition channel from said received test signal;
• and
• a correction unit that automatically calibrates said acquisition channel using said acquisition channel calibration data.
