T50 CT of the 4DCT for the lung/liver phantom in the (a)/(g) axial, (b)/(h) coronal, and (c)/(i) sagittal view, respectively. AVE CTs in the sagittal view for the lung/liver phantom P1/P4, P2/P5, and P3/P6 with motion magnitude of (d)/(j) 0.7/0.5 cm, (e)/(k) 1.3/1.0 cm, and (f)/(l) 2.6/2.0 cm, respectively. The numbers 1, 2, and 3 in (a), and 4, 5, and 6 in (g) indicated proton treatment beam directions. The yellow arrows and dotted lines in the figures indicated the motion direction of the dosimetry inserts and the film locations (three films in the lung phantom and two films in the liver phantom) in the dosimetry inserts, respectively. Abbreviations: T50, 50% phase; GTV, gross tumor volume; PTV planning target volume; IGTV, internal gross tumor volume; AVE, average intensity
