Figure 2From: Theoretical analysis of the dose dependence of the oxygen enhancement ratio and its relevance for clinical applicationsDose dependence of OER for V79 and T1 cells. Dependence of OER on dose per fraction given to hypoxic cells for V79 (Panels A and B) and T1 cell lines (Panels C and D) at low-LET (Panels A and C) and high-LET (B and D). Solid lines show the model calculations for oxygen partial pressures p h in vivo between 0.01 and 20 mmHg (p a = 30 mmHg). Dashed lines correspond to cell experiments in vitro under extreme hypoxia (p h = 0.01 mmHg, p a = 160 mmHg).Back to article page
