General Information

Radiation Onocology at Ochsner Cancer Center of Acadiana utilizes CyberKnife technology. CyberKnife’s robotic, radiosurgery system is the only one of its kind. This approach to fighting cancer treats tumors – and certain other lesions and vascular malformations – anywhere in the body. It can do this without damaging normal tissue as well.

CyberKnife is an FDA-approved total body radiosurgery device made by Accuray®, Inc., developed to treat various tumors throughout the body with extreme precision by utilizing robotic technology and real-time imaging. Patients have been treated with this system worldwide. CyberKnife Center of Louisiana is the only one in southwest Louisiana.

Patient Benefits

The CyberKnife® System is the world’s most accurate radiosurgery device. It can pinpoint tumors and other lesions within millimeters, thereby reducing exposure to healthy surrounding tissue.

Because CyberKnife® is a non-invasive, painless, outpatient treatment, it has significantly fewer complications than traditional open surgery and can often achieve comparable or better outcomes.


  • Treatment complete in one to five days
  • Treatment of lesions that are unable to be removed surgically
  • Lesions that have previously undergone the maximum allowed dose of radiation can be treated
  • Improve comfort due to the elimination of the invasive head-frame
  • Tumor remains targeted using respiratory tracking software
  • Painless
  • No blood loss
  • No scalpel
  • No recovery time
  • Can be used as an additional treatment with surgery and chemotherapy in many cases

Testimonial from Lisa Theriot

Lafayette, LA 
Cancer Patient

For nearly 10 years, I traveled out of state for cancer treatments; it’s difficult to leave your family. But then, I discovered CyberKnife, an amazing radiosurgery that can get into hard-to-reach areas where traditional methods cannot –– and without surgery. I went from pain every day to being pain free. Having this kind of treatment and being able to be home with my family is wonderful.
