IMRT and prediction of tumor induction

1 st problem with IMRT: more beams than 3DCRT

 larger patient volume covered with beams  depending on dose-effect relation, higher risk

P(tumor)

dose

2 plans for the same prostate patient, total dose 78 Gy IMRT 5 beams, 3DCRT 3 beams

of tumor induction risk
