Craniospinal irradiation case
•
A patient was treated with 39 Gy in 13 fractions to the
craniospinal axis.
•
A shift was foreseen after 7 fractions.
•
As result of a mistake an overlap of 1 cm was created
instead of a gap of 1 cm after 7 fractions. This mistake
was applied for 2 fractions.
•
In the overlap region of 1 cm, the spinal cord received
7x 3.1 Gy Dmax and 2 x 6.2 Gy.
