Evaluating the positional uncertainty of intrafraction, adjacent fields, and daily setup with the BrainLAB ExacTrac system in patients who are receiving craniospinal irradiation.

CONCLUSIONS: Position correction is necessary after setup and the transposition of the treatment isocenter. Intra-fraction motion in the lateral direction should be monitored throughout treatment. The position errors in junction areas are almost within the tolerance after correction. The patients did not exhibit any side-effects by the overall treatment.
