From: Investigation of irradiated volume in linac-based brain hypo-fractionated stereotactic radiotherapy
Plots irradiated volume versus target volume using SAHO for single-target data. Left column (a, c, e, and g) are plots for the External (EXT) contour. Right column (b, d, f, h) are plots for the Brain-Minus-PTV (BMP) contour. Top down to bottom row: shows model for 80%, 70%, 60% and50% of the prescription dose. Each dot represents one patient datum point. The best-curve equations according to Eq. (1) (for single-target data) are shown on the graphs. The dashed and dotted lines indicated the 95% prediction and confidence bands, respectively
