Radiation computed tomography apparatus and tomographic image producing method |
摘要 |
A computed tomography (CT) imaging system for improving the image quality of a tomographic image at a predefined image production position in a subject's axis direction in tomographic image reconstruction by axial scanning. The CT system includes an X-ray tube and a detector array configured to conduct a plurality of scans for detecting X-rays passing through a region to be examined around an axis AX of the region to be examined at different positions along the subject's axis Ax direction; and for each of the plurality of scans, and a reconstructing section configured to calculate and reconstruct data for tomographic images of the region to be examined at a position corresponding to a detector row in the axis direction based on detected data acquired in that scan, and combine the data for the plurality of reconstructed tomographic images to generate data for a combined tomographic image at the position corresponding to the detector row.
