Versatile Platform for Image-Guided Radiosurgery


The Novalis Tx™ system has raised the standard for non-invasive, image-guided radiation therapy (IGRT).


Offering clear benefits for physicians and patients, this powerful, state-of-the-art technology is now available through the Cancer Center of Santa Barbara.


“In 2007, we began looking at platforms to replace our linear accelerator,” says Thomas Weisenburger, MD, FACR, radiation oncologist and medical director of the Cancer Center of Santa Barbara. “The Novalis Tx was our clear choice based on its efficiencies and applications for radiosurgery, radiotherapy and image- guided radiation therapy.”

Compared with other technology options, the Novalis Tx requires shorter treatment times to deliver precisely focused, high-energy radiation to a localized area. This capacity makes it ideal for destroying tumors often judged inaccessible via conventional surgery—malignant and benign lesions, brain metastases and arteriovenous malformations—as well as for conditions such as trigeminal neuralgia.


Current Indication

The field size of the Novalis Tx enables it to be used to treat tumors in sensitive locations throughout the body, from brain and spine to genitourinary organs. Another reason for broader usage indications is that the equipment can deliver smaller daily doses for several weeks, a method that retains effectiveness yet minimizes the likelihood of treatment-related injury to sensitive locations.





“The Novalis platform was developed for intracranial conditions. However, its larger field size makes it an ideal system to effectively treat early stage lung cancer and tumors of the spine, liver, pancreas and prostate.”

“If a patient requires fractionated treatment of a benign or malignant tumor in or around the brain, our platform has that capability,” says Dr. Weisenburger. “We can also provide frameless radiosurgery for most brain tumors, an approach that is considerably more comfortable for the patient.”


Further Benefits For delivering IGRT, the platform is unequalled. Its 6-D robotic treatment couch moves in three directions and also tilts and pivots for precise patient positioning. Novalis reduces the time needed to achieve accurate treatment, in most cases from longer than an hour to only minutes.


“As a result of its shortened delivery time, Novalis often eliminates the need to immobilize the patient with a head ring attached to the skull,” says Dr. Weisenburger. “It allows us to achieve unprecedented precision when treating patients with cancers involving the prostate, spine, lungs, head or neck.”


In addition, shared use of Novalis software facilitates collaboration among radiation oncologists, neurosurgeons and referring physicians during IGRT.
