Figures & data
Figure 1. MKB, TV and OF 4D-CBCT reconstructions of the phantom from CBCT scans with target motion of 12 mm and a period of 2.5, 3, 4 and 6 seconds of the mv phase in (a) transversal view and (b) sagittal view.
Figure 2. 3D amplitude of 4D pCT versus 4D-CBCT with the TV and the OF reconstruction for phantom CBCT scans with target motion amplitudes of 6 and 12 mm and periods of 2.5 and 3 seconds.
Figure 3. Examples of TV and OF 4D-CBCT reconstructions for patient 5 and patient 12. A transversal, coronal and sagittal view of the mv phase is shown. The tumor is visible for patient 5, while for patient 12 the tumor is impossible to visualize due to reconstruction artifacts.
Figure 4. 3D amplitude for 2–3 fractions for the 15 patients in which, 4D-CBCT reconstruction was possible. (a) 4D TV CBCT versus 4D OF CBCT, (b) 4D-pCT versus 4D TV CBCT, and c) 4D-pCT versus 4D OF CBCT. In b and c points related to different fractions are connected by vertical lines.
