Varian, BrainLAB Introduce New Stereotactic Radiosurgery System

September 18, 2007 - Varian Medical Systems, Inc. and BrainLAB announced at the Congress of Neurological Surgeons (CNS) meeting in San Diego, CA, that they have teamed up to create Novalis Tx, integrating radiosurgery technologies from both companies for imaging, treatment planning and treatment delivery.

Novalis Tx integrates Varian's Trilogy Tx linear accelerator and new HD120 multi-leaf collimator offering 2.5-millimeter leaves for finer beam shaping. The Novalis Tx radiosurgical instrument will use a variety of standard and configurable options including Varian’s On-board Imager device, the BrainLAB ExacTrac X-Ray 6D room mounted X-Ray imaging system, BrainLAB iPLAN treatment planning software as well as Varian's Eclipse treatment planning and ARIA information management software.

The Novalis Tx offers a wide range of treatment options for several indications, including malignant and benign lesions, brain metastases, arteriovascular malformations and functional lesions. It features high dose delivery rates, dynamic beam shaping and frameless patient positioning. The Novalis Tx reportedly allows multiple beam energies from 6 to 20 million electron volt (MEV) for treating deep-seated tumors and sparing surrounding healthy tissue more effectively. Clinics should be able to treat twice the number of patients per day than with any other radiosurgery system on the market.

The Novalis Tx offers the most comprehensive image guidance system available, including Varian's machine-mounted 3D CT scanner with 2D radiographic and fluoroscopic imaging capability as well as BrainLab’s room-mounted X-Ray imaging system for real-time imaging and motion management. Coupled with BrainLAB’s 6D robotic couch, this system offers an extremely fast and accurate solution for setting up and verifying proper patient position during treatment.

The treatment planning and information management software products present clinicians with the fastest, most user-friendly and versatile platform for managing, planning and delivering radiosurgery.
