Fig. 3. Comparison between the measured and calculated head scatter factor (Sc) values for fixed jaw defined fields of (a) 10×10 cm2, (b) 15×15 cm2, and (c) 20×20 cm2. Sc is calculated based on the dual-source model (DSM) and DSM in conjunction with the multi-leaf collimator (MLC) scatter source (DSM+MLC).
