摘要 |
<p>In order to allow slice thicknesses to be set for a twin asymmetric scan in which a scan is performed with a first slice thickness in a first detector row of a multi detector and with a second slice thickness different than the first slice thickness in a second detector row, first, a position of an X-ray beam is moved and a scan is performed while keeping the width of the X-ray beam fixed at twice the first slice thickness to move the position of the X ray beam to a position at which count values for the first and second detector rows match (ST2 - ST5). The count value for the detector row at this time is stored (ST6). Next, the position of the X-ray beam is moved and a scan is performed while keeping the width of the X-ray beam fixed at the sum of the first and second slice thicknesses to move the position of the X-ray beam to a position at which the count value for the first detector row matches the stored count value (ST7 - ST9). <IMAGE></p> |
