Abstract:
A CT value of an image within a region of interest is calculated with time. While the calculated CT value does not exceed a predetermined threshold value, a reconstruction mode used when an image is reconstructed from projection data is set to half reconstruction. On the other hand, while the calculated CT value exceeds a predetermined threshold value, the reconstruction mode is set to segment reconstruction.
