Abstract

PURPOSE:To reconstitute a perfect image having a small matrix size even during taking of a magnetic resonance signal by successively changing the intensity change order of a phase encoding inclined magnetic field from the intensity necessary for an image having a small matrix size in a phase encoding direction to the intensity necessary for an image having a large matrix size. CONSTITUTION:A 90 deg.-pulse RF1 is applied under an inclined magnetic field GZ1 for a slice to excite the spin of the predetermined slice surface in an object to be examined and a 180 deg.-pulse RF2 is applied under an inclined magnetic field GZ2 for a slice is applied to perform 180 deg. reversal. A phase Gy is applied before a spin echo signal R is obtained and a spin echo signal R is obtained under a frequency encoding inclined magnetic field GX2. The above-mentioned imaging period is repeated while the intensity Ge of the phase encoding inclined magnetic field Gy is changed so as to satisfy a formula gammaLeintegral Ge.dt=2npi. Therefore, when the spin echo signal R of phase encoding quantity of n=2<i>/2 is already obtained at the point of time when imaging is interrupted, an image of 2<i>X2<i> or an image of 2<i>XF (F: a matrix size in a frequency encoding direction) can be reconstituted.
