Fig. 4From: An investigation into the range dependence of target delineation strategies for stereotactic lung radiotherapyPhantom target volumes versus range of movement. PTV segmented from FB, FB-Aug, AIP and MIP 4DCT image sets are compared with respect to the 10 phase benchmark. A ± 0.5 cm tumor amplitude is represented by 1 cm target range. The negative slope associated with the FB method is attributed to the temporal resolution of the CT imaging systemBack to article page
