Figure Lengend Snippet: GTV displacement of patient 8. Both the sagittal (left) and axial (right) views are taken at the level of the maximum tumor volume. The planning GTV (yellow) is delineated on the planning CT, and PGTV (red) is generated with a 6 mm expansion. All the GTVs (blue) contour from the FBCT were mapped to the planning CT after rigid registration with respect to bony anatomy.
Article Snippet: Prior to each treatment fraction, diagnostic‐quality fan‐beam CT (FBCT) scans were acquired using Philips Spectral CT 7500 (Philips Healthcare, Best, The Netherlands) and GE Revolution CT (GE HealthCare, Chicago, IL, USA).
