Figure 7.6

(a) Transaxial image with manual segmented tumor contours in the reconstructed CBCT at one respiratory phase of a lung dataset (patient 3). The contours were used for 3D centroid calculation. (b) Tumor meshes in the Fréchet mean CT (white), in the target CBCT at the EE respiratory phase (blue) and in the CLARET-estimated CT (red) of a lung dataset (patient 2). The background is a coronal slice of the mean CT for illustration. The overlap between the estimated and the target tumor meshes indicates a good registration.
