Radiation therapy, or radiotherapy, has seen many advances in recent years. There are numerous technologies available now much to the benefit of both radiation oncologists and patients. Each technology and treatment option has their place in the treatment plan catered to your unique condition. One such option is TomoTherapy.



TomoTherapy combines Intensity Modulated Radiation Therapy (IMRT) with computed tomography (CT) in one treatment machine. This advanced technology allows radiation oncologists to create a 3D scan of the tumor, measuring and confirming the location of the tumor.

Once the tumor’s exact location has been determined, the radiation beams are then delivered in “slices,” treating one layer of the tumor at a time. Each day you receive TomoTherapy treatment, the size, location, and shape are verified before treatment begins, ensuring that the tumor receives the majority of radiation doses, which will minimize exposure to surrounding structures, tissues, and organs.

TomoTherapy is especially noteworthy in treating:

  • Breast cancer
  • Colon and Rectal cancers
  • Lung tumors
  • Prostate cancers
  • Head and Neck cancers
  • And more
