Abstract
When the diagnostic center position and a reconstruction FOV are designated using a tomographic image, a system control device controls a top plate of a table to move from side to side and up and down so that the designated diagnostic center position reaches the center position of scanning. A scanner is provided with a plurality of compensation filters configured to adjust X-ray irradiation distribution, and the system control device selects a proper compensation filter according to the designated reconstruction FOV from among the plurality of compensation filters, switching to the selected compensation filter. The compensation filters include at least a compensation filter (size L) of wide-width X-ray irradiation distribution and a compensation filter (size S) of narrow-width X-ray irradiation distribution in a scanner-turning direction. When the designated reconstruction FOV is a predetermined threshold or less, the compensation filter is switched to the S-sized compensation filter.
