Radiation Treatments

CT Simulation

Enhances radiation treatment planning by generating three-dimensional images for utmost accuracy in targeting and mapping specific treatment areas. With Virtual CT Simulation, oncologists can deliver high doses of radiation to a tumor, while minimizing the amount of radiation to normal, surrounding tissues.

Treatment planning is enhanced with the use of a three-dimensional treatment planning computer. Using the information and images provided by the Virtual CT Simulator, the computer generates a treatment plan tailored to the patient's cancer care needs. Guided by three-dimensional models, the physician, physicist and dosimetrist can accurately determine the most effective dose of radiation to be delivered during treatment.

Image Guided Radiation Therapy (IGRT)

A procedure that uses a computer to create a picture of a tumor to help guide the radiation beam during radiation therapy. The pictures are made using CT, ultrasound, X-ray, or other imaging techniques. Image-guided radiation therapy makes radiation therapy more accurate and causes less damage to healthy tissue. Also called IGRT.

Intensity Modulated Radiation Therapy (IMRT)

This therapy uses computer-generated images and treatment planning to deliver high doses of radiation to a tumor, while minimizing the amount of radiation to normal, surrounding tissues. The higher dose to the tumor can result in a higher possibility of cure, and the lower dose to surrounding tissue results in fewer side effects.

Imaging Fusion

This technology enhances radiation treatment planning by enabling oncologists to more precisely and confidently locate and define tumors. With Imaging Fusion, oncologists can scale, rotate, and translate images into 3D for an accurate perspective of their size and shape.

High Dose Rate Brachytherapy (HDR)

This therapy uses a radioactive source that is placed inside the body part to be treated. Then, a high dose of radiation is given to a limited area, sparing the surrounding normal tissue. HDR brachytherapy lasts only a few minutes in the outpatient setting and causes little discomfort, fewer complications, and a more rapid recovery time.

Low Dose Rate, Permanent Interstitial Prostate Seed Implant

Radioactive sources that are placed inside the prostate to destroy cancer cells.

Accelerated Partial Breast Irradiation (APBI) SAVI® Breast Brachytherapy

The SAVI® breast brachytherapy applicator is the latest advancement in the delivery of radiation treatment for women with early-stage breast cancer. Arizona Oncology Radiation is designated as a Center of Excellence in accelerated partial breast irradiation (APBI) for offering this advanced technology.

Breast brachytherapy is an approach that uses radiation to treat the lumpectomy cavity and the surrounding tissue from within the breast.  SAVI allows your radiation oncologist to precisely deliver radiation where it is needed most.

If you have been diagnosed with early-stage breast cancer, you might be eligible for 5-day radiation therapy with SAVI. provides access to important information about the SAVI applicator and partial breast radiation, as well as the opportunity to learn more from the women who have already experienced treatment with SAVI. 

Stereotactic Body Radiation Therapy (SBRT)

This therapy is a type of external radiation therapy that uses special equipment to position a patient and precisely deliver radiation to tumors in the body (except the brain). The total dose of radiation is divided into smaller doses given over several days. This type of radiation therapy helps spare normal tissue.

Stereotactic Radiation Therapy (SRT)

A type of external radiation therapy that uses special equipment to position the patient and precisely deliver radiation to a tumor. The total dose of radiation is divided into several smaller doses given over several days. Stereotactic radiation therapy is used to treat brain tumors and other brain disorders. It is also being studied in the treatment of other types of cancer, such as lung cancer. Also called stereotactic external-beam radiation therapy and stereotaxic radiation therapy.


Mammosite is a specific type of HDR Brachytherapy which specifically is used to treat breast cancer. It utilizes an inflatable balloon temporarily placed in a lumpectomy site at the time of surgery or in some cases, 2-3 weeks later and then followed by twice daily treatments over 5 days of just a few minutes a day where only the resected area of the breast is targeted.


Contura is a type of radiation balloon called a multi-lumen balloon or MLB. Contura contains five separate lumens or tubes inside the balloon. The additional lumens help your doctor to shape or contour the radiation dose away from the skin or chest wall to obtain a more optimal result. Your doctor may be able to better target the radiation to the areas in most need of treatment and keep it away from healthy tissue and organs to help minimize side effects caused by the radiation.

SpaceOAR Hydrogel

Placed between the prostate and rectum, SpaceOAR Hydrogel reduces rectal injury in men receiving prostate cancer radiation therapy (RT) by acting as a spacer – pushing the rectum away from the prostate, out of the high dose radiation region.
