Impact of nominal photon energies on normal tissue sparing in knowledge-based radiotherapy treatment planning for rectal cancer patients
Fig 1
The target DVHs of 20 patients, as optimized automatically using various photon energies.
Subfigures (a-d) present the target DVHs of 6X, 6F, 8X and 10 F (dotted lines) relative to the reference 10X results (solid lines) respectively. The figure-in-figure shows the corresponding mean target DVHs of 20 patients, as optimized using the same beam energy.
