Fig. 2. Comparison of dose distributions in transverse planes for lung flattened beam plan (left) and flattening filterfree plan

(right), with planning target volume outlined in red. The dosevolume histogram shows similar planning target volume coverage

and organ at risk sparing between 6-MV flattened beam plan (squares) and 10-MV flattening filterfree plan (triangles).
