PROBLEM TO BE SOLVED: To provide an MRI device to be used as a signal receiving high-frequency coil with a plurality of coil elements combined, in which inspection time for the signal receiving high-frequency coil is shortened. SOLUTION: A real time system 100 varies combination of coil elements and allotment to channels every echo using a pulse sequence for collecting data without applying a phase encoding. A host system 200 computes a correlation value between data reconstituted by channels and reference data, and determines the combination of the coil elements as abnormal when the correlation value is smaller than a prescribed threshold value. The host system 200 carries out level correction to collected data, and forms an alternative to the abnormal combination of coil elements, including decrease of the number of channels.
