Abstract

An MRI system center is connected to a plurality of MRI systems for visualizing the interior of a subject to be examined using a magnetic resonance phenomenon, through an electronic communication line. The MRI system center receives data of a log file on which a use state of the MRI systems is recorded or use-state data extracted from the log file, from the MRI systems through a communication control unit. A database unit stores the data of the log file or the use-state data. An analysis unit analyzes the data of the log file or the use-state data received within a given period of time.
