摘要：
The present invention is intended to improve the quality of a tomographic image to be produced by an X-ray CT apparatus including an X-ray area detector represented by a multi-array X-ray detector or a flat-panel detector. A conventional (axial) or cine scan is performed on the first and second scanned positions in the direction of a z axis. Projection data items produced by scanning the first scanned position and projection data items produced by scanning the second scanned position are used to reconstruct a tomographic image.
