Radiation tomography apparatus

The present invention relates to a tomographic image by preventing deterioration even when a plurality of scattering radiation generated and prevents artifacts to improve the quality of the tomographic image. X- ray detector arrays corresponding to the area not shielded collimator X- ray detecting element to obtain a first detection data. In this case, first detection data generated by irradiation: from X- ray tube is irradiated by X- ray imaging subject directly to X- ray detecting element; X- ray tube and the X object as imaged by the scattered radiation -Rays. In addition, X- ray detector arrays corresponding to the detection data obtained by the second detecting element X- ray collimator shielding region. In this case, the second detection data generated by the X- ray as scattered radiation. The central processing unit based on the corrected detection data comprises first detection data and second detection data first. Finally, the central processing unit generates a tomographic image of the imaging region of the imaging subject.
