Table 4 Global gamma pass rates comparing the sCT and CT dose distributions using a 15% dose cut-off

From: Clinical validation of a commercially available deep learning software for synthetic CT generation for brain

Gamma criteria Gamma pass rate ± 1 S.D. (%) Range (%)
3%, 3 mm 100.0 ± 0.0 99.9–100.0
2%, 2 mm 99.8 ± 0.2 99.1–100.0
1%, 1 mm 99.1 ± 0.6 97.9–99.8
1%, 1 mm (PTV) 100.0 ± 0.0 99.9–100.0
