Photon and proton treatment plans for a representative patient over the age of 15 (this patient was 16 years old, index 13). (a) Proton dose distribution in the sagittal plane. (b) Photon dose distribution in the sagittal plane. (c) Proton dose distribution in axial planes from the cervical spine to the sacral spine in 5-cm increments. (d) Photon dose distribution in axial planes from the cervical spine to the sacral spine in 5-cm increments. (e) Isodose scale for both photon and proton treatment plans.
