Your treatment with radiation involved a simulation being carried out.

Treatment with radiation is also called radiotherapy. Your radiotherapy involved the use of special radioactive substances. When these radioactive materials break down, they produce radiation. This is why these substances are also referred to as radiation sources. Your radiotherapy involved the radiation sources being placed very close to the areas needing to be treated. The rays only work in the immediate vicinity of the radiation sources and are intended to destroy diseased tissue there. This is to protect the surrounding tissue as much as possible.

The best approach for your radiotherapy was tested with the help of a special device. This is also known as simulation. CT images of your body were produced during this simulation. This is to make the subsequent radiotherapy as precise and safe as possible for you.

A CT scan involves sending X-ray beams through the body. Measurements are then taken to see how much of these beams are getting to the other side of the body. A computer then converts the measurements into images of the inside of the body.
