What is Radiosurgery?
Types of Radiosurgery
Stereotactic radiosurgery is radiosurgery to the brain.
Stereotactic body radiotherapy refers to radiosurgery delivered to areas of the body outside the brain.
Radiosurgery is a specialized form of radiotherapy using extremely precise targeting of X-rays. No actual cutting is involved with radiosurgery, making it useful for treatment to various parts of the body.
Radiosurgery can be used to treat certain cancerous tumors or benign conditions to relieve troublesome symptoms associated with some conditions. Typically, radiosurgery is most appropriate for small tumors confined to a particular organ.

Novalis and Novalis Tx Radiosurgery
The most advanced model of the existing Novalis radiosurgery system is Novalis Tx. Cleveland Clinic is the first hospital in Ohio to install and clinically use the state-of-the-art Novalis Tx.
Both Novalis and Novalis Tx are powerful, high precision radiosurgery systems equipped with the ExacTrac X-ray 6D imaging system.
Novalis Tx is versatile for treating patients with a wide spectrum of tumor sizes, locations and types. Novalis Tx features:
- Sub-millimeter accuracy for super-conformal radiation treatments, such as intensity modulated radiotherapy, stereotactic body radiotherapy and radiosurgery
- High-definition beam shaper of the most fine resolution thereby protecting the normal tissue around the tumor
- Ability to form each radiation portal with a high resolution while maintaining the radiation focal point within 0.5 mm accuracy when the radiation beam rotates around the patient
Three different imaging devices:
- ExacTrac X-ray 6D system
- volumetric kilo-voltage cone beam computed tomography (CT) system
- mega-voltage portal imaging system
These imaging technologies allow millimeter accuracy in pinpointing the tumor location before and during treatment. With continual imaging guidance during the treatment to detect movement, the newly designed robotic treatment couch provides precise and efficient correction in patient positioning.
With the increased radiation output and enabled volumetric delivery, Novalis Tx can deliver the most complicated treatment plans efficiently.
Best System for Each Patient
For patients with small lesions such as in early stage lung cancer or spinal metastasis, both Novalis and Novalis Tx systems can achieve the same treatment accuracy and precision with real-time image guidance based on the bony anatomy.
For patients with large tumors, the extended radiation collimation size of Novalis Tx (40 cm in Novalis Tx; 10 cm in Novalis) provides for accurate, efficient treatment of patients.
For patients undergoing treatment that requires soft tissue localization, the kilo-voltage volumetric cone-beam CT imaging in Novalis Tx offers 3D anatomical information and soft-tissue contrast for more accurate tumor localization and patient positioning.
