摘要: A computerized tomography apparatus is disclosed which reconstructs a tomography image of data from multi-directional projection data in a period of time less than the time required for a scan operation for data acquisition and displays the tomography image after a lapse of a given period of time from the termination of the scan operation. This avoids the time interval between scan and image display becoming irregular. Accordingly, tomography images can be displayed successively like motion picture to observe the internal movements of a section of a human body under examination in real time.

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.
