Impact of nominal photon energies on normal tissue sparing in knowledge-based radiotherapy treatment planning for rectal cancer patients
Fig 2
The DVH differences of the OARs as optimized using various beam energies relative to 10X photons.
The dashed lines plot the data of 20 patients, and the solid lines are their average. The left and right column shows the results of 6X-10X and 8X-10X respectively. Subfigures (a-b), (c-d), (e-f), (g-h) and (i-j) plot the results for the urinary bladder, femoral heads, NTID, skin and small bowel respectively.
