TBI Treatment

In TBI treatment, the

1) prescribed dose is about 1200 cGy, generally delivered using POP of fields
2) dose is delivered as a single fraction
3) dose is delivered as multiple fractions, 10 to 15 cGy per fraction

High dose TBI is delivered in a single fraction or in a small number of fractions of 200 cGy/fraction, 6 fractions for a total 1200 cGy.

Low dose TBI is delivered in 10 to 15 fractions of 10 to 15 cGy per fraction. For further study see Podgorsak.
