Selected RT-HT cell survival curves of HCT116 cells heated at various times at 47 °C fitted by the LQ part of the AlphaR model (left). For better visualisation of the data, curves are shown with the respective off set in survival after HT treatments. The corresponding fit parameters α (middle) and β (right) for all survival curves listed in Table 1 are shown as a function of thermal dose. Thermal dose t₄₃ was calculated according to Equation (10) under the assumption of a constant RBE calculated using Equation (11), and the respective values for α₀ as indicated in Figure 3.
