Figure 3From: A comparison of liver protection among 3-D conformal radiotherapy, intensity-modulated radiotherapy and RapidArc for hepatocellular carcinomaThe comparison of DVHs for normal liver in 3DCRT, IMRT and RA for the larger tumor. Right figure: DVHs of PTV. These three techniques produced similar homogeneity of the PTV and 3DCRT obtained highest volume of hot spot. Left figure: DVHs of normal liver. RA obtained the highest low-dose distribution in the normal liver compared with 3DCRT and IMRT. However, 3DCRT obtained the highest high-dose distribution in the normal liver compared with IMRT and RA.Back to article page
