Trilogy Accelerator

Meeting a higher set of standards

Trilogy Accelerator. Meeting a higher set of standards.

Trilogy is the first practical, clinically-viable system for delivering all forms of external-beam radiation therapy. It enables doctors to choose and use the most appropriate treatment modality for treating cancer in the body or the head and neck, and to deliver the full spectrum of treatments, all on one machine in a single room.

Built on the solid foundation of the Clinac iX platform the Trilogy is a fast, versatile and comprehensive delivery system. Trilogy represents a cost-effective means of expanding the patient case mix and treatment modality repertoire within a radiation oncology department.

Delivery system components
  • The Trilogy configuration of the Clinac iX accelerator
  • Exact IGRT couch
  • Millennium 120-leaf MLC with dynamic MLC capability
  • RPM respiratory gating system
  • LaserGuard collision detection system
  • 4D Integrated Treatment Console
The Trilogy accelerator has all the capabilities of a Clinac 21EX or 23EX plus the following new features:
  • Stereotactic mode (6MV beam, up to 1000MU/min dose rate, up to 6000 MU/field total dose, up to a maximum field size of 15cm x 15cm, and up to 60MU/deg dose rate for arc-based treatments)
  • 0.5mm radius isocenter for gantry and collimator axes
  • 0.75mm radius isocenter for all three rotational axes (gantry, collimator and couch)
  • Remote couch motion
    • Small translations and small rotations (less than 2 cm and 2 degrees) for fine-tuned setup corrections
    • Large rotations for remotely sequencing between non-coplanar arcs

Tight isocentre alignments on all three axes. Targets the smallest lesions.

Trilogy leads in beam accuracy for treating increasingly smaller tumors anywhere in the body. On two axes (the gantry and the collimator) Trilogy's isocentric accuracy measures 0.5mm or less. Add the third rotational axis (the couch) and the isocenter radius is 0.75mm or less, the tightest alignment available in a dual energy system.

Maximize efficiency: a common approach to integration

Trilogy takes advantage of the common approach to integration taken for granted in today's Varian products. This gives you the advantage of information presented in a consistent way, available when and where you want it throughout Varian's Aria information oncology system. In addition, training overhead is reduced as staff are familiar and confident using all aspects of the equipment. Greater accuracy is achieved as the same patient positioning systems can be used throughout the planning and treatment process. Ease of use is a priority.
