Fig. 2

Representation of the deformation vector field of a patient (a) on a sagittal slice in DIBH. The arrows show the direction of expansion between DIBH and FB. The difference between the V20 contours of the left lung in FB and DIBH is presented in (b). The green area shows V20 in FB and the yellow outline V20 in DIBH, which was deformed to the FB CT. As can be seen there are differences in the location of irradiated lung volumes. A comparison of DVH and MDH of the left lung for a patient is plotted in (c)
