Intensity-Modulated Radiation Therapy (IMRT)

If you are diagnosed with certain tumors of the head and neck, brain, lung, prostate or other types of tumors, Jefferson offers one of the largest radiation programs for cancer treatment in the Delaware Valley. Surgery is the primary therapy for many of these conditions, and radiation therapy plays an important role before or after surgery.

What Does Intensity-Modulated Radiation Therapy Involve?

Radiation therapy for your cancer may be given in the form of intensity-modulated radiation therapy (IMRT), which delivers radiation doses that precisely fit the 3-D shape of a tumor. It also tightly regulates the intensity of the radiation to more closely target the tumors and spare surrounding tissue. Jefferson was the the first in the Delaware Valley to use IMRT.

Radiation is usually delivered by dividing the treatment into multiple (usually five to nine) angles. IMRT further divides each beam into smaller squares. This allows more control over how the radiation is delivered. IMRT customizes radiation delivery to your body and your tumor. This allows for:

  • Better tumor coverage
  • Safer delivery of higher doses of radiation
  • Better field shaping
  • Fewer side effects

What Does Intensity-Modulated Radiation Therapy Require?

  • Detailed imaging – You may need to get one or more CT, MRI, PET or other scans to help the physician know where the tumor is to target.
  • Making sure the patient and tumor do not move during treatment.
  • An expert team to define the tumor, plan how to treat the cancer and manage any side effects.

Our radiation oncologists subspecialize in tumor types and specialized therapies and are seeking to improve outcomes of cancer patients, in part through carefully combined and sequenced therapies.

We have the team to provide you with unsurpassed multidisciplinary care that is coordinated between your radiation oncologist, surgical oncologist and/or medical oncologist.

TrueBeam System: Ensuring Radiation Therapy Accuracy

At the Bodine Center for Radiation Therapy, we have two TrueBeam™ systems. This linear accelerator, or LINAC, is capable of delivering fast and precise 3-D image-guided radiotherapy for the treatment of cancer. Treatments focus powerful radiation on the tumor while limiting exposure to surrounding healthy tissues.

TrueBeam is able to deliver radiation through many forms of advanced techniques including IMRT. Treatments that once took 10 to 30 minutes can now be completed in less than 2 minutes.

A TrueBeam System is also available at our Riddle, Pa. location, and a new TrueBeam STx Slim with BrainLab Novalis was installed at Jefferson Hospital for Neuroscience in August 2014.
