摘要： 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.

摘要： According to the present invention, a subject is prompted to take breaths that are different at least in depth, and the subject's motion associated with respiration is captured. A timing when the subject is scanned is controlled according to the captured motion of the subject associated with respiration. A two-dimensional detector formed like a two-dimensional plane detects an X-ray beam having passed through the subject. Data is collected from the two-dimensional detector to acquire volume data on the subject.
