Radiobiological Framework for the Evaluation of Stereotactic Radiosurgery Plans for Invasive Brain Tumours

Figure 2

Delineated targets from Figure 1 and patterns of infiltration assumed in this study. Cell density outside the target is assumed to decrease as function of the distance to the target (upper panels) or have a more heterogeneous pattern of infiltration (lower panels). The colour scale indicates the relative density of clonogens, from 1 inside the target volume to zero outside the target if the distance from the border of the target exceeded 10 mm.
