Radiation Oncology

Approximately 50 percent of all cancer patients will require radiation as part of their cancer treatment plans. Radiation therapy used high-energy radiation to destroy the cancer cells' ability to divide and multiply. It can precisely target specific tumors without damaging the surrounding tissue.
Radiation oncologists are the specialized physicians who treat patients needing radiation therapy. At the Providence, we offer the expertise of board-certified radiation oncologists who offer the latest treatment technologies.

Services include:

  • Intensity Modulated Radiation Therapy (IMRT) is a type of 3-dimensional radiation therapy that uses computer-generated images to show the size and shape of the tumor. Thin beams of radiation of different intensities are aimed at the tumor from many angles. This type of radiation therapy allows us to further reduce the damage to healthy tissue near the tumor.
  • RapidArc/VMAT (Volumetric Modulated Arc Therapy) is a form of IMRT treatment that is delivered as the treatment machine rotates in an arc around the patient. The intensity of the thin beams of radiation is continually changing to precisely deliver the treatment as the machine rotates.
  • 3D Conformal Radiation Therapy is a radiation technique that uses computers to create a 3-dimensional picture of the tumor so that multiple radiation beams can be shaped to conform to the treatment area.
  • Image Guided Radiation Therapy (IGRT) uses special imaging technology to pinpoint, with millimeter accuracy, the precise location of a targeted tumor for daily treatments. IGRT can compensate for any tumor motion during treatment by ensuring that the treatment beam is precisely aimed at all times.
  • Respiratory Gating allows for correlation of tumor position in relation to the patient’s respiratory cycle. Using a special tracking system we can deliver radiation treatments during a specific portion of the breathing cycle or during a breath hold.
  • Stereotactic Radiosurgery is an extremely conformalized delivery of radiation to tumors while ensuring maximal protection of the surrounding normal structures. Treatments are delivered in a single session or a limited number of sessions and because of its precision, higher doses of radiation are able to be delivered than with conventional radiotherapy techniques.
  • Radioactive Seed Implants (RSI)/Brachytherapy is a procedure in which radioactive material sealed in needles, seeds, wires, or catheters is placed directly into or near a tumor. Brachytherapy is also known as internal radiation, implant radiation, and interstitial radiation.
