3 & 4 Dimensional Radiation Therapy

A procedure that uses a computer to create a 3- or 4-dimensional image of the tumor to allow physicians to locate and dose high amounts of radiation to the area. By knowing the size and location, a single area may be focused upon, thus minimizing radiation exposure to healthy tissue.

Some of our specific 3 & 4 dimensional radiation therapy options include:

  • IGRT- Image-Guided Radiation Therapy
  • IMRT- Intensity Modulated Radiation Therapy
  • 3-D Conformal Therapy
  • Stereotactic Radiosurgery
  • SBRT- Stereotactic Body Radiation Therapy

Brachytherapy (radioactive implant)

Radiation Therapy at Capital Medical Center is the only provider between Portland and Tacoma to offer brachytherapy.

Also referred as internal radiation, brachytherapy uses a radioactive implant inserted near or in the tumor. The radiation released from the implant only travels a short distance, minimizing radiation exposure to healthy tissue. The implants are inserted into the body using a catheter.

Some of our specific brachytherapy options include:

  • HDR- High Dose Rate Brachytherapy – temporary implant
  • SAVI Partial Breast Irradiation
  • Prostate Implants
  • Gynecologic Implants – interstitial and intercavitary


Radiation Therapy at Capital Medical Center is the only provider between Portland and Tacoma to offer hyperthermia treatment.

Is a treatment where tissue is exposed to high temperatures, up to 113° F. It is nearly always used in conjunction with another form of cancer therapy (e.g. chemotherapy or radiation therapy) because it may make the cancer cells to be more sensitive to the radiation. Hyperthermia can also enhance the effect of certain cancer drugs.


Our board-certified chief radiation oncologist, Dr. Randy Sorum, leads a team of highly trained health care professionals.
