Percentage depth dose curve

In Radiotherapy, one of the dosimetry processes involves characterising the clinical radiation beam by measurement of the variation of dose with depth (z) in a water phantom, for all energies and field sizes.

Dose is then normalised to d_max (the depth of dose maximum) and a plot of relative dose versus depth in the phantom is produced.
