The invention provides a magnetic resonance image pickup device, a magnetic resonance image pickup maintenance device, a magnetic resonance image pickup maintenance system and a magnetic resonance image pickup device check method, wherein a real-time system uses pulse sequence to collect data without applying phase coding, aiming at combination of each echo variation coil element and allocation for channels. After that, a host system computes the data for restructuring each channel and associated value of reference data, and judges the combination of the coil element as abnormality when the associated value is less than the stated threshold value. In addition, the host system performs electric level correction to the collected data and produces an alternative proposal for the abnormal combination of the coil element on condition of containing situation of the number of the reduced channels.
