Abstract
A radio frequency pulse to excite nuclei constituting an object to be imaged, a slice selecting gradient magnetic field pulse applied when the radio frequency magnetic field pulse is applied, a phase encoding gradient magnetic pulse, a frequency encoding gradient magnetic field pulse are applied to the object to be imaged placed in a static magnetic field. Then the generated nuclear magnetic resonance signals are detected many times to form an image of the internal structure of the object to be imaged using the detected signals. In this occasion, the amplitude of the slice selecting gradient magnetic field pulse or the width of the radio frequency pulse is changed corresponding to the amount of phase encoding given by the phase encoding gradient magnetic field pulse. In multi-slice imaging for detecting the signals from a plurality of slices spatially laminated, part of the signals are used in common between the slices adjacent to each other when two-dimensional images of those slices are reconstructed.
