Axxent eBx or Xoft

The Axxent electronic brachytherapy (eBxTM) is a type of radiotherapy that utilizes a minaturized high dose rate X-ray source to apply radiation directly to the cancerous site. The goal is to direct the radiation dose to the size and shape of the cancerous area, sparing healthy tissue and organs.

The Axxent technology is painless and usually takes only a few minutes and for most cancers is given in eight separate doses.

This electronic brachytherapy therapy provides new options for:

  • Patients with cosmetically sensitive lesions not interested in or unable to have surgery.
  • When resection of larger lesions on the lips, eyelids or ears is difficult or impossible for necessary function.
  • More desireable cosmetic outcomes.

CT Large Bore Technology

The University of Arizona Department of Radiation Oncology recently enhanced its radiation program by introducing the Phillips Brilliance CT Big Bore. The Brilliance CT Big Bore cutting-edge innovation enhances the process of detection, diagnosis and treatment of cancer, and provides solutions to help clinicians confidently affect patient care and reduce costs.

The 85cm bore size enables the ability to scan patients with immobilization devices, patient monitoring, intravenous delivery devices and respiratory devices without compromising image quality or positioning. The large bore CT allows for flexible treatment setups and comprehensive motion management tools to improve confidence in treatment volume assessment.

With the Brilliance Big Bore CT scanner technology, we truly enter the multislice arena now and for the future.

Novalis Delivery System

Novalis is a state-of-the-art treatment device for patients undergoing stereotactic radiosurgery or fractionated stereotactic radiotherapy. Stereotactic radiosurgery is applied in a single session with a high dose of radiation. Fractionated stereotactic radiotherapy is administered in a series of treatment sessions over a specified period of time.

With Novalis, the radiation beams are shaped to match the exact contour of the tumor or lesion so that even irregularly shaped tumors or lesions can receive doses of radiation totally consistent with that prescribed. Sophisticated software calculates the ideal access points to the tumor or lesion and defines the treatment plan.

Novalis can be used to treat areas of the body such as the brain, lung, liver, prostate and spine to improve and increase the range of a patient's available treatment options.


The Department of Radiation Oncology at the University of Arizona is one of the few hospitals in the Southwest to offer the TomoTherapy HiArt® treatment system, a new way to deliver radiation treatment for cancer. TomoTherapy involves the safe delivery of high radiation doses to a very small, targeted area.

A truly integrated approach to radiation therapy

The Tomotherapy system integrates imaging with radiation treatment, allowing physicians to verify the position of the tumor immediately before each treatment session. This way, adjustments can be made on the spot to make sure that radiation is delivered exactly where it should be. This is important because tumors can move and change shape and size quickly.

Traditional radiation therapies project radiation on a tumor from a few directions. With Tomotherapy,  the Radiation Therapy Team can deliver precise and powerful doses of radiation therapy from 360 degrees.

Even if patients have reached their maximum tolerance dose of traditional radiation, or if their tumor is in a hard to reach area, Tomotherapy may open new doors to advanced treatments.

The equipment used for Tomotherapy looks much like a computed tomography (CT) system. The patient lies on a couch that moves continuously through a rotating ring gantry. The gantry houses a linear accelerator, which delivers radiation in the shape of a fan beam as the ring is turning. With the couch moving at the same time the gantry is rotating, the radiation beam makes a spiral (or helical) pattern around the patient, targeting tumors with optimal levels of radiation while minimizing the dose to healthy areas.
