An effective calibration technique for radiochromic films using a single-shot dose distribution in Gamma Knife

Highlights • Film calibration using an existing reference dose distribution was proposed. • Proposed method produced a physically equivalent calibration curve. • A virtual target treatment plan for Gamma Knife radiosurgery was assessed. • Gamma index pass rates were used to verify the accuracy....
