PROBLEM TO BE SOLVED: To suppress the formation of a virtual image caused by difference in measurement phases between measured data by calculating the measured data matching their phases when measuring signals a plurality of times and adding them together in a magnetic resonance imaging device measuring the signals while holding a steady state. SOLUTION: A center frequency is measured before and after or during measuring the signals, the center frequency in measuring the signals is calculated to find a phase error of the detected signals. Alternatively, the phase of the signals detected near the echo peak of the measured signals is calculated to find the phase difference between the measurements. After matching the phases between the measured data by rotating the found phase error amount relative to the measured data, the data are added. COPYRIGHT: (C)2004,JPO&NCIPI
