Simulation &
Treatment Planning
Prior to your first treatment, x-rays or CT scans will be taken of
the area. This is done with a special
unit called a simulator. A simulator is a treatment planning machine
which enables Dr. Maddock or Dr. Lane to determine the precise location
of your treatment field. It does not deliver the actual treatment.
Once the location of the
treatment area has been established, the skin surrounding the area
is marked with small tattoos about
the size of the head of a pin. This ensures that the exact same area
is treated during each visit.
Simulation not only permits precise localization, it also helps to
determine whether treatment shields are needed to protect surrounding
organs or tissues. Treatment shields are
unique to each patient and are made using the simulator films or CT
scans as a guide. Additionally, depending on the area that is being
treated, the therapists may use a customized casting to help you maintain
a particular position with comfort during simulation and treatment.
Treatment Planning
Once simulation is complete, computer calculations are used to determine
the best method of delivering the prescribed amount of radiation. Since
radiation affects all cells, normal and abnormal, treatments are calculated
to attack the area of involvement while sparing as much normal tissue
as possible.
