PROBLEM TO BE SOLVED: To reduce sensitivity nonuniformity of a reconstruction image caused by an RF receiving coil and the like without substantially elongating an imaging time in a multistation 3D MRI repeating the imaging while moving a table such as a whole body MRI. SOLUTION: This MRI equipment receives a nuclear magnetic resonance signal generated from a subject using the RF receiving coil at a first relative position between the RF receiving coil and the subject; performs a three-dimensional measurement thinned with an encode step in a phase encoding direction, on respective signals obtained by impressing a slice encode; obtains measurement data under the first slice encode formed with aliasing by the RF receiving coil; changes the relative position between the RF coil and the subject and receives the nuclear magnetic resonance signal at a second relative position; obtains the measurement data under the second slide encode formed with aliasing by the RF receiving coil; and removes aliasing components included in the respective slice encoding data in a computation using a receiving sensitivity distribution of the RF receiving coil taking account of the relative position between the subject and the RF receiving coil, thus providing the 3D image.
