PURPOSE: A method is provided to shorten the echo time, achieve improved resolution and reduce noises by reducing the size of the dephasing gradient of frequency coding axis. CONSTITUTION: A method comprises a step of receiving an image signal of an object at the state where the frequency coding gradient is decreased in such a manner that a ringing artifact is not generated; and a step of receiving the shortened echo time and image data of improved resolution and restoring the same. The frequency coding gradient is a dephasing gradient of frequency coding axis.
