Figure 6b. Images obtained with computed dosimetric reconstruction. (a) Isodose line image used for planning standard anteroposterior-posteroanterior radiation therapy. The area of highest radiation dose is indicated by the magenta line around the border of the right chest wall (arrows). (b) Isodose axial image used for planning 3D conformal radiation therapy in another patient. The area of highest radiation dose is indicated by the aquamarine line immediately surrounding the tumor. With 3D radiation therapy, the highest radiation dose is delivered to the tumor; with standard radiation therapy, the highest dose is at the chest wall.
