From: Clinical utility of Gafchromic film in an MRI-guided linear accelerator
Relative and absolute gamma evaluation comparing Monte Carlo-derived planned dose distributions with Gafchromic EBT3 film irradiated in the MR-linac environment using various field sizes. Dose difference/distance-to-agreement criteria of 3%/3 mm (blue), 3%/1 mm (orange), and 3%/2 mm (grey) were used. Gamma values exceeded 90% pass rate for all field sizes
