<p>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 (A1) by an axial scan or helical scan using the detector, raw data ( d1 ۥ d6 ) of three or more adjacent detector rows collected using a multi-row detector having three or more detector rows are multiplied (A2) by cone-beam reconstruction weights ( Wi ) and Z-filter weights ( wi ), and are added to obtain one projection datum ( Dg ). Backprojection processing is applied (A3) to the projection datum ( Dg ) to obtain a pixel datum.</p> |
