CyberKnife® Radiosurgery

Precise, non invasive cancer treatment with robotic accuracy

CyberKnife is a robotic system that delivers highly targeted radiation to tumors anywhere in the body. It uses robotic movement, real time tumor tracking and AI-driven guidance to follow the tumor and adjust treatment as needed. This allows doctors to treat cancer without incisions, hospitalization or lengthy recovery. 

MercyOne Richard Deming Cancer Center offers Iowa’s only flexible stereotactic radiosurgery system (SRS). CyberKnife is the only SRS system that uses robotic technology and image guidance to treat tumors that were once considered inoperable — without the need for rigid restraints or added discomfort for patients.

How CyberKnife Works 

CyberKnife uses a small linear accelerator (a machine that delivers radiation) attached to a flexible robotic arm. It can position radiation beams from thousands of angles, shaping treatment around even complex tumors while protecting healthy tissue

CyberKnife can reach areas of the body that are difficult to treat with traditional surgery or radiation, including the brain, spine, prostate, liver, lungs, head and neck. It requires no anesthesia and carries fewer risks than surgery. It can also provide hope for patients who may have received the maximum allowable dose of radiation or have been told their condition is untreatable. 

The Synchrony® tracking system adjusts for breathing and body movement in real time, ensuring radiation remains locked on target throughout treatment.

Benefits of CyberKnife Treatment 

  • Non invasive treatment with no incisions and no need for rigid frames or restraints to stabilize patients
  • Fewer sessions, Cyberknife treatments can be completed in just 1 to 5 sessions, compared to 30 to 40 sessions required for conventional radiation therapy
  • Shorter treatment times, many completed in as little as 15 minutes
  • Sub millimeter accuracy, protecting surrounding healthy tissue
  • Minimal side effects due to steep dose falloff and precise targeting
  • Faster return to daily life with little to no downtime

CyberKnife is used for tumors and conditions throughout the body, including:

  • Brain tumors
  • Lung cancer
  • Liver tumors
  • Pancreatic cancer
  • Prostate cancer
  • Spinal tumors

Your care team will develop a personalized plan using advanced imaging. CyberKnife then delivers precise, painless radiation while you rest comfortably. Most patients resume normal activities immediately.
