Abstract
An image reconstruction apparatus of the present invention comprises units for measuring projection data from a number of angular directions within an angular range less than 180.degree. with respect to a subject, a unit for performing parallel displacement of the projection data so that the subject may substantially be located within a specific region corresponding to said angular range, a unit for calculating a Fourier coefficient for expanding the displaced that into a Fourier series, and units for reconstructing a slice image of the subject by means of the calculated Fourier coefficient.
