PROBLEM TO BE SOLVED: To display the actual movement of an examinee in real time by providing a display means for freeze-displaying at least finally obtained image data among a series of image data from an image reconstitution means for reconstituting image data from multi-directional projection data. SOLUTION: At the time of photographing operation, an X-ray tube and a detector array are continuously rotated first to execute continuous scanning, and when raw data required for reconstituting a sheet of tomographic image data are collected under control of a CPU 22, these raw data are transferred to a reconstitution part 32 from a memory 36. Then, when reconstitution of a sheet of a tomographic image is finished, tomographic image data are written in a display memory 34. In addition, the present tomographic image is displayed on a CRT monitor 7 in a frozen state until the timing of reconstituting and displaying the next tomographic image. Next, when a single operation of continuous scanning is finished, raw data in the memory 36 are stored in a magnetic disk 38. |
