Intensity Modulated Radiation Therapy (IMRT)

Your doctor has chosen Intensity

Modulated Radiation Therapy or IMRT as

the type of radiation therapy that you will

receive. IMRT uses a high-energy x-ray

beam to destroy cancer cells or keep them

from growing.

• With IMRT, the strength of the

radiation beam can be adjusted

which allows your doctor to give

high doses of radiation to the tumor

and avoid nearby healthy tissues.

• A more tightly focused beam of

radiation dose can be delivered to

tumors than with other radiation

therapy.

• Your doctor will decide if the

entire treatment course will be

given using IMRT or if IMRT will

be combined with conventional

radiation therapy.

Radiation treatments are painless.

You will not feel anything while

you are being treated.

PREP

Preparation for IMRT

• During your first planning visit, a special positioning device will be made for you. The

device is used to help you stay in the same position for each treatment.

• A CT scan will be done in the treatment position, using the device. The scan will help

your doctor map out the area to be treated.

• Marks may be put on your skin to help position you for treatment.

• After your CT, you may go home.

• Your doctor will spend the next several days designing your treatment plan. The CT

scan is used along with a computer to develop the best possible treatment plan.

• When the plan is complete, you may be scheduled to return for a simulation.

• Simulation is a separate appointment that may be needed before you begin treatment.

X-rays are taken with you in the treatment position exactly as you will be during

treatment. The steps in simulation are based on the IMRT plan that was made for

you. When you are finished, you will be given an appointment to return for your first

treatment.

IMRT Treatment

• Daily treatments, are given in the

linear accelerator room by a team

of Radiation Therapists.

• Each treatment lasts between 15

and 30 minutes.

• Much of that time the therapists

will be making sure that you are in

the correct treatment position.
