An evaluation of Pencil Beam vs Monte Carlo calculations for intracranial stereotactic radiosurgery.

CONCLUSION: It was found that the difference between systems is often not enough to cause the plan to fall outside of RTOG protocol deviation limits. This is an indication that a PB-based treatment planning system is sufficient for the mostly homogeneous conditions of intracranial SRS planning when the target is larger than 0.1 cm3. If below 0.1 cm3, the prescribing physician may need to evaluate TPS differences. PMID: 33455120 [PubMed - in process]
