After the initial consultation, a treatment simulation is performed in order to gather more information about the location and size of the tumor. This simulation can greatly enhance the accuracy of your treatment.. CT simulation allows the radiation oncologist to directly visualize your particular anatomy and treat only the targeted tissue while identifying and avoiding critical structures. This greatly reduces unwanted side effects.
On the day of your first treatment, you will be positioned with a immobilization device on the treatment table. The TomoTherapy machine adjust the treatment table and deliver the high-energy beam according to your specific programmed treatment plan.
The actual treatment may take five to fifteen minutes to complete. You will not feel anything during the treatment, and you will not see any movement of the machine, which is shaped like a large CT scanner. During the treatment, the high-energy Linear Accelerator within the machine will be rotating in a pattern of a CT scan and will be continuously changing to shape itself to your anatomy. This process will be repeated for every one of your treatments to assure the greatest precision and accuracy. Your radiation therapists lead this process.
Radiation treatments are typically given daily, Monday through Friday.
Your radiation oncologist and other members of your treatment team carefully study the information gathered during the simulation to better understand your specific case and to determine the appropriate course of treatment. Taking your general medical condition into consideration, your treatment team uses computer-aided technology to develop a plan that provides the safest and most effective treatment for you.
