title: Helical tomotherapy for craniospinal radiation.
abstract: Helical tomotherapy (HT) plans for craniospinal radiation were generated for the case of a 4-year-old boy with disseminated ependymoma. The HT plans demonstrated excellent target coverage, homogeneity and organ sparing compared with a conventional linear accelerator based craniospinal radiation plan. On the basis of this case study, further evaluation of HT for craniospinal radiotherapy seems justified.
