|Novalis Tx is the newest advance in Stereotactic Radiosurgery (SRS) and Stereotactic Body Radiation Therapy (SBRT). It offers the patient the most versatile treatment platform available for radiosurgery and stereotactic body radiotherapy. Novalis Tx has "Robotically controlled" treatment table and can perform most Radiosurgery in a frameless mode avoiding the discomfort of the surgical placement of the treatment frame required by other less sophisticated systems. The Novalis Tx carries out radiosurgery of cranial lesions as well as performs extra-cranial treatments to the spine, lung, liver, pancreas and prostate with accuracy and precision unsurpassed by any other methodology.
To further enhance the technological superiority of this treatment delivery system, the UCLA Novalis Tx is equipped with Varian's RapidArc radiotherapy technology. RapidArc is the most advanced and most rapid method to deliver radiation to its intended target. The speed of the UCLA Novalis Tx system allows for better precision of the treatment delivery while enhancing patient comfort by decreasing the treatment time.
The UCLA Novalis Tx treatment platform includes three distinct imaging/target localization modalities for pinpointing the tumor/target and positioning the patient with the highest precision - the On-Board Imaging device (OBI) which allows 3-D cone beam CT visualization of the treatment target, ExacTrac image-guidance system which provides continual imaging during treatment to detect minute patient movements which are then corrected by robotic adjustments in patient positioning in six dimensions, and Electronic Portal Imaging Device (EPID) for precise localization and patient set-up using the treatment beam itself. These methods allow for protection of surrounding healthy tissues while enabling your radiation oncologist and surgeon to precisely concentrate higher, more effective doses to the tumor or lesion.
Novalis Tx offers treatment options for an extremely wide range of indications such as malignant and benign lesions in the brain including primary brain tumors, brain metastasis, arteriovascular malformations, as well as treatment of functional neurological conditions. In addition, Novalis Tx, through its dynamic ultrafine beam shaping, non-invasive precise frameless patient positioning system, and ultra-rapid treatment delivery, can treatment difficult to treat malignant and benign diseases of the spine, lung, liver, kidney, pancreas and prostate.
Novalis Tx offers Robotic control, Frameless non-invasive localization of the target, and the greatest speed available for treatment delivery. These features allows for the maximum in precision and highest level of patient comfort.
With the installations of the world's first Novalis system for shaped beam radiosurgery in 1997, UCLA continued its pioneering efforts to provide the highest levels of patient care. Novalis, a dedicated system for non-invasive stereotactic radiosurgery and stereotactic radiotherapy (SRS and SRT), represents cutting-edge technology for treatments of the highest precision. Novalis is equipped with "Novalis Body" software for image-guided radiotherapy delivery. Its X-ray-based localization technology allows physicians to localize tumors with sub-millimeter accuracy and to position patients automatically and with the highest degree of precision.
Shaped Beam Radiosurgery is the most advanced form of stereotactic radiosurgery. Beam shaping results in a high target conformality (better exclusion of normal tissue conforming the dose only to the intended target) as well as better dose homogeneity (i.e., no "hot or cold spots" of dose). Novalis produces a sharp radiation dose gradient at the treatment field edges resulting in a highly effective treatment of the target, while greatly reducing the dose of radiation to the surrounding healthy tissue. This non-invasive treatment can often avoid complications and inconveniences of open surgery. A treatment with Novalis typically takes less than 30 minutes.
Why is Shaped Beam Radiosurgery Better? The "old" technology utilizing multiple isocenters (left) spreads more dose to healthy tissues as well as creating hot spots within the target. Hot spots can cause necrosis (death) of normal tissue and other complications. With shaped beam technology (right), critical structures are better protected from the complications caused by "hot spots".
