ABSTRACT:
For the purpose of obtaining an image having a large slice thickness, such as a thickness twice or three times the size of a multi-row detector as measured in the Z′-axis direction, based on raw data collected by an axial scan or helical scan using the detector, raw data (d1-d6) of three or more adjacent detector rows collected using a multi-row detector (24) having three or more detector rows are multiplied by cone-beam reconstruction weights (Wi) and Z-filter weights (wi), and are added to obtain one projection datum (Dg). Backprojection processing is applied to the projection datum (Dg) to obtain a pixel datum.
