Timpanogos Cancer Services in collaboration with GammaWest Cancer Services provides the best radiation oncology therapies available in Utah County. Services include various modalities of:

  • Tomo Therapy
  • Brachytherapy

Tomo Therapy

Timpanogos Regional Hospital now provides image-guided, intensity modulated radiation therapy (IG-IMRT), more commonly called Tomo Therapy. As of October 2019, this system installed at Timpanogos Regional Hospital is the most up-to-date and effective technology of its kind in Utah County.

What it is

It is the only radiation therapy system designed on a CT scanner foundation embedded with advanced radiation technology. The image-guided system uses images from CT scans to design external radiation beams that conform to the shape of the tumor by delivering beams from many directions.

How it works

Tomo Therapy takes images of the tumor right before treatment sessions to precisely target the tumor. Conventional radiation therapy machines deliver a wide beam of radiation from only a few angles. In contrast, our image-guided system is calibrated to deliver radiation from all angles for accurate radiation treatment. The Tomo Therapy technology modulates the dose of radiation so the strength of the beams are adjusted to give higher doses of radiation to the tumor while sparing normal tissue.

Our radiologist team will help you onto the system’s screening bed and have you lie on your back. The bed will move you through the CT machine to reveal the location and size of the tumor. Our oncology team then puts together a plan by using your CT images and special software that determines the size and shape of the tumor and its proximity to sensitive organs and tissues. Our oncology doctor then prescribes how much radiation the tumor should receive. Based on the prescribed dose, the Tomo Therapy system calculates the appropriate position and dosage. Once again, the bed will move you through the CT machine to receive the radiation treatment.

Tomo Therapy treats many types of cancer

Indications for use of the Tomo Therapy system include: Intracranial, Head and Neck, Lung, Breast, Spine, Pancreas, GYN/GU, Prostate, Superficial, Sarcomas, Total Marrow Irradiation (TMI), Total Body Irradiation (TBI) and more.

The system is capable of treating all standard radiation therapy cases including breast, head and neck, prostate, and lung cancers, in addition to complex treatments such as total marrow irradiation.


If you have been diagnosed with cancer, it's natural to feel concerned and even a bit frightened. You probably have many questions concerning treatment choices and decisions. Most likely, you find yourself constantly thinking, "How am I going to cope with side effects and when will I feel better again," followed often by "What can I do to prevent the cancer from returning?"

Brachytherapy involves the placement of radiation directly at the site of the cancerous tumor. A key feature of brachytherapy is that the radiation only affects a localized area around the radiation source. The specificity of brachytherapy results in patients receiving more precise and efficient treatment. Brachytherapy was brought to Utah County first at Timpanogos Regional Hospital.
