Further additions
The SSD dependence have to be added
The dose due to bremsstrahlung was originally subtracted from the
measured depth–dose curve.
o
This must now be added back to the electron dose, after putting back
11
the inverse square law dependence.
o
It is assumed that the dose beyond the depth of the practical range is
entirely due to photons.
