Also listed is the ratio of each SD to its respective dose value. Each organ was contoured in its entirety. In addition these data are presented separately for age specific target volumes, i.e., CSF space (including index 13, 15, 17, and 18) or CSF space and vertebral bodies (VB) (all remaining indices).
