Abstract
An NMR imaging apparatus for reconstructing a cross section of a body to be inspected, by the projection-reconstruction method. That is, an apparatus for forming the above cross section in such a manner that the nuclear magnetic resonance is caused by the to-be-inspected body in the resulting magnetic field of a static magnetic field and a rotatable gradient field, a projection of the to-be-inspected body is detected at each rotational positions of the gradient field, and the cross section is reconstructed using the above projection. The apparatus comprises memories for previously storing therein data indicating the distorsion of magnetic field such as the non-uniformity of the static magnetic field and the non-linearity of the gradient field, in order to perform the coordinate calculation in the back projection, using the data stored in the memories.
