RADIATION IMAGING APPARATUS AND RADIATION IMAGING METHOD |
摘要 |
Embodiments of the present invention improve image quality by preventing artifacts from developing. From the projection data obtained by performing a scan for the imaging area of a subject, a tomographic image for a cross-sectional plane of the imaging area is reconstructed. Based on the tomographic image, the density distribution of the imaging area of the subject is then calculated. Thereafter, the scattered radiation beam data is calculated depending on the density distribution, and the projection data is corrected using the scattered radiation beam data. Finally the corrected image is reconstructed based on the corrected projection data.
