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 results of a dose calc. algorithm (here: CC) of a widely used commercial TPS...

typical challenges for all dose calculation algorithms: small fields, irregular shaped fields (esp. off-axis), high energies (15MV and more)

measured depth dose curve

calculated depth dose curve, 1mm voxel size

calculated depth dose curve, 3mm voxel size
