What is Alliance Radiosurgery?

Alliance Radiosurgery delivers state-of-the-art radiosurgery services for the treatment of cancerous and non-cancerous conditions throughout the body.

As one of the most advanced, nonsurgical cancer treatment options available, radiosurgery is changing the face of cancer care and helping people to continue working, spending time with family and friends, and taking part in their favorite activities, all while fighting cancer.

Alliance Radiosurgery uses the latest technology advances from Elekta and Brainlab to enable sophisticated approaches to traditionally challenging cases. The system’s patented technology provides superior conformance to tumor size, shape and volume, allowing clinicians to administer higher dose rates that can enhance treatment effectiveness, while protecting critical structures such as the heart, spine, or bladder. The result is highly precise treatments with shorter treatment times, and the ability to offer highly advanced therapies while minimizing the impact of treatment on our patients’ quality of life. Shortened treatment times can also improve patient comfort, particularly for our older patients who may find it difficult to remain in one position over extended periods of time.

Alliance Radiosurgery Benefits


  • Advanced, versatile 2D, 3D and 4D image guidance and soft tissue visualization before and during treatment ensures accurate patient positioning and target localization.
  • The radiation beam is shaped precisely to the tumor or lesion, ensuring maximum dose to the target while protecting surrounding healthy tissue.


  • Alliance Radiosurgery provides SRS & SBRT treatments delivered in as little as 15-20 minutes for a more comfortable patient experience compared to other radiosurgery treatment options.
  • Rapid treatment reduces the likelihood of patient or target movement, ensuring the highest possible level of treatment accuracy.
  • Treatments can be delivered in single, hypofractionated, or fractionated sessions, based on physician recommendations.


  • Flexible treatment options – frameless or frame-based; single or multiple fractions; circular or conformal beams; dynamic conformal arcs or intensity modulated radiation therapy (IMRT) & volumetric modulated arc therapy (VMAT)—ensure the best treatment for each individual patient and condition.
  • Choose flattened beams or high dose rate mode, depending on the location of the tumor or lesion inside the body or brain.
  • Alliance Radiosurgery offers hope to patients with inoperable clinical conditions and those that were once considered untreatable.


  • Frameless radiosurgery offers a more patient-friendly treatment experience compared to a frame-based procedure.
