A method is provided for performing a quality analysis of a radio frequency (RF) coil of a magnetic resonance imaging device. In an operational mode, the RF coil is configured to acquire MR signals from an object to be observed. In a test mode: a test signal is emitted by a RF transmitter; the test signal from the RF transmitter is received directly by the RF coil, wherein the RF coil provides an output signal; and a performance indicator is provided by analyzing the output signal of the RF coil for performing the quality analysis.

Method and magnetic resonance imaging device for performing a quality analysis of a radio frequency coil

A method for monitoring a high-frequency transmit device of a magnetic resonance tomography system with a transmit antenna system having a plurality of transmit channels is provided. A reference transmit signal is output on different transmit channels of the transmit antenna system, respectively, at different time points, and a reference measurement signal induced by the reference transmit signal is measured on at least one of the other transmit channels using a measuring device assigned to the transmit channel. Based on the reference measurement signal, a phase deviation indicator value is determined. The phase deviation indicator value indicates a relative phase deviation between the measuring devices of the transmit channels in question.
