“It is clear that using a
type B
algorithm, it is more difficult to
conform the planned dose to the PTV than using a
type A
algorithm, especially for a small PTV.”
•
This is caused by the increased influence of lateral scatter
disequilibrium for smaller PTV, which is modeled better using a
type B algorithm.
•
Thus,
a less strict conformity requirement is formulated for
type B
.
