ABSTRACT:
An image reconstructing method in relation to an X-ray CT apparatus for shifting, sequentially by a predetermined angle, a reconstructed image for a projection angle in a predetermined range so as to obtain a continuous reconstructed image, in which one normal reconstructed image is obtained as follows: First, 180.degree. amount of parallel beam projection data, which is obtained by converting fan beam measurement data into parallel beam data, is divided at a predetermined angle so as to obtain each partial reconstructed image for each partial segment. Then, weight-imposing is performed on the plurality of partial reconstructed images obtained, and the weight-imposed images are superposed, thus obtaining the one sheet of normal reconstructed image. At that time, concerning partial reconstructed images the view angles of which are in an opposing relationship to each other, a weighted average thereof is determined.
