IMRT Course 2016

Precise dose calculation is still a challenge:

Be aware of potential software BUGS!

Example:

depth dose curve

in water

for a central

1x1 cm field

, 6MV

typically challenges for all dose

calculation algorithms:

small fields, irregular shaped

fields (esp. off-axis), high

energies (15MV and more)
