Treating tumors means targeting areas that are subject to motion and changes in position and size. ExacTrac® Snap Verification uses x-ray images, acquired during treatment delivery or between fields, to instantly detect and visualize internal tumor displacement and patient movement. The result is real-time intra-fraction motion management.
- Instantly ready at any couch or gantry angle and during beam-on
- Threshold-based margin analysis
- Highest precision for single fraction treatments like cranial and spine SRS
- IGRT solution with real-time intra-fraction motion management

Instant verification and correction at any position
ExacTrac Snap Verification uses x-ray images acquired during treatment delivery for intra-fraction verification of the tumor position. A threshold-based margin analysis algorithm indicates whether patient setup correction is needed. ExacTrac automatic couch control can then be used to remotely realign the patient.
- Accurate targeting from beginning to end of each fraction
- Software-integrated instant imaging and verification
- Immediate detection and visualization of intra-fraction tumor motion

Patient comfort with Frameless Radiosurgery
|
|
| Frameless Stereotactic Radiosurgery | ExacTrac® Frameless Radiosurgery replaces frame-based treatments, offering highly accurate delivery of single fraction treatments for improved patient comfort. ExacTrac uses stereoscopic x-ray imaging combined with the Brainlab stereotactic immobilization system and a three-piece, non-invasive mask to provide sub-millimetric precision.
- Improved flexibility for imaging, planning and treatment
- High accuracy with non-invasive positioning

Robotic Couch Capabilities for improved
setup accuracy | The ExacTrac® Robotic Patient Alignment allows the highest precision patient set-up in six degrees of freedom. Mounted on top of the treatment couch, the Robotic Patient Alignment system is fully integrated and operated by the ExacTrac system to correct setup errors.
- Allows for automatic correction of rotational misalignments
- Provides greatest level of setup accuracy
- Particularly suitable for complex setups such as cranial, head & neck, or spine indications
- ExacTrac Robotics may currently be retrofitted to Varian Exact couches
