From: Volumetric intensity-modulated Arc (RapidArc) therapy for primary hepatocellular carcinoma: comparison with intensity-modulated radiotherapy and 3-D conformal radiotherapy

Figure 1

The comparison of isodose distributions of PTV and OAR in 3DCRT, IMRT and RapidArc. A: 3DCRT, B: IMRT and C: RapidArc. RapidArc achieved better conformality to the 95% isodose line (red line) of the PTV and better spinal cord sparing to the 50% isodose line (yellow line) as compared with 3DCRT and IMRT. However, RapidArc obtained higher 30%-isodose coverage (blue line) of volume of the normal liver than did 3DCRT and IMRT.
