Fig. 11From: Dosimetric study between a single isocenter dynamic conformal arc therapy technique and Gamma Knife radiosurgery for multiple brain metastases treatment: impact of target volume geometrical characteristicsDose fall-off (%/mm) representation as a function of the volume and the isodose line for GP (a) and MBM (b). Figure (c) illustrates the GP vs MBM dose fall-off: the left figure illustrate in 3D the dose fall-off absolute values as a function of the volume of the PTV and the isodose percentages selected, the right graph indicates the absolute dose fall-off difference. The white areas are for differences not statistically significantBack to article page
