Figure 2

Dose maps of 2-dir interlaced planar minibeams (cf. Fig. 1c) with homogeneous (a) and heterogeneous (c) tumor dose. The dose is color-coded with saturation at 15 Gy. The cross-section of dose and the local clonogenic cell survival at 10, 45, 90 and 100 mm depth are shown for homogeneous (b) and heterogeneous (d) tumor irradiation with 10 Gy mean or minimum tumor dose, respectively. Heterogeneous tumor irradiation is described in section III.B.
