Computed tomography method utilizing a conical radiation beam |
摘要 |
The invention relates to a computed tomography method where the examination zone is scanned by means of a conical radiation beam. The reconstruction volume can be enlarged by reconstructing the absorption of voxels in a first sub-volume by means of a first reconstruction algorithm and that of voxels in a second sub-volume by means of a second reconstruction algorithm, the assignment of the voxels to the sub-volumes being performed in such a manner that the secondary conditions for the reconstruction algorithms used for these sub-volumes are satisfied.
