After your second appointment, the radiation oncologist will carefully design your treatment plan using the imported CT images from your simulation. Three-dimensional planning computers show the size and shape of the targeted tumor from all angles. This technology assists the radiation oncologist to determine the exact points at which radiation will enter your body, minimizing exposure to surrounding normal tissues. This makes it possible to prescribe the precise doses of radiation needed.
The information collected during your treatment planning is processed by the dosimetrist, who uses sophisticated computer software to calculate the radiation doses prescribed by the radiation oncologist. The treatment planning process may take several days. Your final treatment plan is reviewed by both the physicist and the radiation oncologist before you return for your next visit.
