At the heart of TrueBeam advanced performance is the proprietary Maestro synchronous control system that dynamically directs, synchronizes, and monitors all TrueBeam integrated functional components including the treatment beam generation, gantry, collimator, couch and imaging to enable seamless system operation. Maestro’s sophisticated orchestration and command of every element of treatment delivery including dose, motion and imaging enables fast and efficient image-guided treatments including SRS gated RapidArc. Sub-millimeter accuracy1 and comprehensive QA tools help ensure patient safety and delivery conformality.
On TrueBeam’s flexible open architecture, clinicians can interface with multiple technologies for imaging and disease-specific solutions. The integration of MV, kV, and optical imaging modalities means that the TrueBeam can support a wide variety of imaging and treatment delivery techniques. A combination of 2D, 3D, and 4D imaging capabilities allows for imaging to be both flexible and customizable. The system continuously monitors tumor movement and helps clinicians deliver radiation only when the tumor is in the right place, while the patient continues natural breathing.
Advanced imaging techniques include:
- Blended MV/kV radiographs
- Respiration-synchronized fluoroscopy and cine MV
- Respiratory-synchronized MV and kV radiographs
- kV image acquisition during treatment delivery
- 4D CBCT
Enhanced Imaging treatment techniques, all of which can be delivered under respiratory gated conditions, include:
- RapidArc radiotherapy technology
- Dynamic conformal arc
- Visual Coaching Device
