Radiation therapy uses high energy particles or waves to destroy or damage cancer cells in a specified area. For most people, treatments are given 5 days a week for 1 to 7 weeks. The number of treatments you need depends on the size and type of cancer, where the cancer is, how healthy you are, and what other treatments you are getting. External radiation therapy is like getting an x-ray. It is painless and only takes a few minutes. The side effects of radiation therapy vary depending on where the radiation is directed.

New, advanced technology combined with our experienced, knowledgeable physician team and staff means your treatments are on par with facilities across the Northwest. All the cancer care and services a patient needs are located here under one roof: medical oncology, radiation oncology, infusion therapy, financial counselors, social work and a cancer nutritionist. This level of care provides you the opportunity to stay at home during treatments.

Portneuf Cancer Center-Radiation Oncology

The Elekta Infinity is utilized to deliver daily radiation treatments to our patients. The machine has the ability to perform a variety of treatments that range from simple electron treatments to complex 3D and IMRT treatments. The utilities also allow for our radiation therapist and doctor to visualize the tumor and normal tissues on a daily basis through a cone beam CT.

Toshiba Aquilion Large Bore CT  is utilized to CT the patient in treatment position. The large bore allow for more freedom in set-up position.

Treatments offered:

  1. 3D conformal
  2. IMRT Intensity Modulated Radiation Therapy
  3. VMAT Volumetric Modulated Arc Therapy 
  4. IGRT Image Guided Radiation Therapy
  5. SBRT- Stereotactic Body Radiation Therapy is a treatment which target a well-defined tumor with a very high dose of radiation over a short period of time.
  6. SRS-Stereotactic Radiosurgery- is TBD
  7. Left Breast patients who qualify are treated utilize a deep-inspiration breath hold technique to help push the heart away from the treatment field.

Radiation Treatment Process

What to expect at the time of consultation?

The consultation with the Radiation Oncologist will be an opportunity to visit with the Dr. about your diagnosis and the ways your cancer can be treated. Cancer is treated with a multi-disciplinary approach. This allows the patient the opportunity to visit with all three aspects of your care (Surgeon, Medical Oncologist, and Radiation Oncologist).

What to expect on the day of your radiation simulation (Sim)?

The simulation will take place in the radiation oncology department. You will be greeted by a radiation therapist who will instruct you on what to change into for the simulation. You will be accompanied back to the CT simulator where you will be set-up in the treatment position which you will receive your radiation therapy treatment in. This position varies depending on where the cancer is located.

What to expect on the first day of treatment?

The first day of treatment will be the longest appointment after the CT simulation. The first day of treatment will include the treatment itself and a verification simulation (V-Sim) on the treatment machine. The V-Sim will verify you are in the same position as the original simulation and verify that the trajectory and shape of the treatment beams are correct.

What to expect for your on treatment visits (OTVs) with doctor during treatment?

Once a week during radiation treatments the physician and nurse will meet with you to discuss and address questions and concerns that you may have during the treatment process.
