Target Volume Delineation for Pediatric cancers
Recent developments in radiation and neuro-oncology provide the ability to deliver required radiation dose to target volumes for pediatric brain tumors while avoiding sensitive normal central nervous system (CNS) structures uninvolved by tumor. Many CNS target volumes are smaller than in previous years due to better understanding of areas at risk for recurrence or involvement and patterns of spread for a given diagnoses. Advances in neuroimaging and treatment planning software allow for better delineation of tumors and normal neuroanatomy
