Varian Medical Systems and BrainLAB teamed up to create Novalis Tx, which integrates Varian’s Trilogy Tx linear accelerator and new HD120 multi-leaf collimator, offering 2.5 mm leaves for finer beam shaping. The Novalis Tx radiosurgical instrument uses 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.
It offers multiple beam energies from 6 to 20 million electron volts (MEV). For image guidance, it features a machine-mounted 3D CT scanner with 2D radiographic and fluoroscopic imaging capability as well as room-mounted X-Ray imaging system for real-time imaging and motion management. A 6D robotic couch assists patient positioning. The treatment planning and information management software is for managing, planning and delivering radiosurgery.
