    摘要: A plurality of regions of interest can be set to be monitored. From a keyboard (17) or a mouse (19), ROI position information and CT value conditions for the ROI's are set to a ROI position information memory (39) and a ROI condition memory (21), respectively. An image reconstruction system (9) reconstructs data of a first scan stored in a projection data memory, displays as a reconstruct image (59) on a display device (13) via an image memory (11), and calculates individual representative CT values of the ROI's set as the ROI position information, storing in the image memory (11). A condition decision section (43) of a CPU (15) makes decisions of whether the representative CT values of the ROI's meet the conditions in the ROI condition memory (21), executes an operation between respective results of the decisions to decide whether the first scan is to be continued or shifted to a second scan.
