How Novalis Works
The Stereotactic Radiosurgery (SRS) Department at Northern Westchester Hospital combines ground-breaking technologies and world-class medical expertise to deliver targeted, non-invasive radiation treatments using the Novalis System.
We've prepared this overview to help you and your family learn about how Novalis works, and the advantages it offers over traditional radiosurgery. We've also included information about how our team of radiation oncologists, neurosurgeons, and medical specialists use this SRS system to deliver life-changing treatments to patients with primary cancers, malignant and non-malignant tumors, and even some conditions that were previously considered untreatable.

What Is Radiosurgery?
Despite the name, radiosurgery is very different from traditional, open surgery. Using a specialized delivery system, a team of radiation oncologists treat various types of cancer and other conditions with large doses of radiation.
Radiosurgery is also known as radiation surgery, stereotactic radiation therapy, and stereotactic radiosurgery (SRS).
What Is The Novalis Varian TrueBeam?
The Novalis is a complete SRS system that brings together cutting-edge imaging systems, robot-assisted motion management tools and a high-precision, shaped beam radiation delivery device. This combination of advanced technologies allows our radiosurgeons to treat your tumor with exceptional accuracy, even if your tumor is located in an otherwise inoperable area or is irregular in shape.
During your treatment, your medical team can adjust the intensity of the radiation during delivery while protecting surrounding, healthy tissues from damage. In many cases, even aggressive tumors can be successfully treated in a single session using the Novalis System.
How Do Traditional SRS Systems Work?
Traditional stereotactic radiosurgery systems use circular-shaped beams of radiation to target the tumor or lesion; this can result in less-than-accurate coverage of the treatment areas, since most tumors are not perfectly round and even. With some SRS systems, the strength of the beam must be set prior to the treatment, and it cannot be adjusted once the radiation delivery begins.
Older, less sophisticated SRS systems also require time-consuming movements made by radiologists in an attempt to manually adjust the circular beam to match the shape and density of the treatment area. This lack of accuracy can result in damage to the surrounding healthy tissue as well as the delivery of lower doses of radiation to the outside edges of the tumor or lesion.
Am I A Candidate?
Whether or not the Novalis System can be used to treat your specific condition depends on a number of factors, including your diagnosis, whether or not you have already undergone conventional radiation treatments, and your co-current conditions.
You may have your case reviewed by the NWH Tumor Board - a multidisciplinary team consisting of pathologists, radiation oncologists, surgeons, and other cancer experts who meet weekly to discuss patient treatment plans.
Here at NWH, we're using Novalis radiosurgery to treat both cancerous and non-cancerous conditions, including:
- Trigeminal neuralgia
- Cancerous tumors and metastases of the prostate, liver, lungs, and brain
- Arteriovenous malformations (AVM)
- Spine tumors
- Brain metastases/gliomas
What Are The Advantages of the Novalis Varian TrueBeam?
When compared to conventional forms of radiation delivery, the Novalis offers a number of advantages, including:
- Increased radiation accuracy as a result of the RapidArc shaped radiation beam, which conforms to irregular, non-circular tumors and lesions while protecting surrounding tissue against damage
- X-ray based localization technology allows surgeons to achieve sub-millimeter accuracy while working around sensitive tissue and organs
- The ability to deliver high doses of radiation deep inside the tumor, brain, or lesions in either a single session, or a series of treatments (known as fractionated radiotherapy)
- Integrated patient monitors automatically adjust the radiation to your breathing, heart rate, and movement to deliver safe, accurate treatment
- Because the Novalis is a frameless SRS system, patients wear only a light, custom-fit mask rather than an invasive, restrictive head ring
- The comfortable, 6-D robotic couch ensures fast, precise patient positioning throughout the treatment
- Most Novalis sessions take about 15-20 minutes to complete, and are performed on an outpatient basis
As an FDA-approved technology, the Novalis Radiosurgery System has been used in hospitals throughout the world for more than 15 years. During that time, it has helped countless patients receive precise, targeted, non-invasive radiation treatments for conditions ranging from spinal cord tumors to cancers of the lung, liver, breast, and prostate.
Here at Northern Westchester Hospital, we're passionate about providing exceptional patient care and personalized treatment options. Our surgeons use innovative, ground-breaking treatments and technologies like Novalis to improve patient outcomes and reduce complications, making recovery from major illnesses and life-threatening diseases easier.
