Fig. 4From: Cerebral cortex dose sparing for glioblastoma patients: IMRT versus robust treatment planningIMRT and robust dose distributions for patient B on a representative CT slice. Left column: IMRT/ robust plan without cortex sparing (wo CS). Middle column: IMRT/ robust plan with cortex sparing (w CS). Right column: dose difference (plan wo CS minus plan w CS). The dose difference shows the potential of cortical sparing of up to 25% (purple area) for this slice. Red and yellow areas indicate a dose reduction of 10%, and 5%, respectivelyBack to article page
