Fig. 3From: Dosimetric comparison of carbon ion radiotherapy and stereotactic body radiotherapy with photon beams for the treatment of hepatocellular carcinomaScatter plot diagram of the diameters of the gross tumor volume and mean liver dose. Stereotactic body radiotherapy could not achieve the dose constraints for normal liver (mean liver dose > 18.8 Gy) in four patients for whom the tumor diameter was more than 4 cmBack to article page
