Before proton therapy, your radiation oncologist will use a CT scan – and possibly an MRI and/or PET scan – to reconstruct the tumor and surrounding areas. This is called a “CT simulation appointment.” By reconstructing the tumor through imaging, your radiation oncologist can plan accurate, precise radiation dosing that targets the tumor while protecting the surrounding normal tissue.
Once your personalized treatment plan is complete, and before your first treatment, you will participate in a “dress rehearsal,” which ensures your positioning and dosage are accurate. Your physician will review every aspect of treatment during this time. If they give approval, treatment may begin either the same day or the next day.
