How to evaluate and find the best strategy?:
Treatment course simulation approaches
treatment plan,
dose distribution
multiple organ contours and
setup errors values
•
either measured in a patient
study
•
and/or simulated based on
motion model
sample N
fractions
(e.g. 35) setup error
values and organ geometries
evaluate and average/sum-up dose
for these N
fractions
samples
repeat thousands
of times
Probability distribution of
organ doses
