Positioning & Target Control
Intrafractional Verification
ExacTrac, a fast and highly accurate X-Ray system, provides detailed target visualization and non-coplanar positioning and monitoring for stereotactic cranial radiosurgery treatments
Frameless Mask & Fixation System
The ExacTrac frameless radiosurgery system ensures highly accurate delivery of single or multi-fraction treatment with a patient-friendly mask that facilitates a streamlined workflow.
- Enhanced cranial immobilization for highly accurate delivery of SRS
- Reproducible conformity with a precise non-invasive stereotactic mask system
- Highly rigid design prevents rotations in pitch and roll
- Compatible with multiple couch tops
- Allows for time-saving and patient-friendly treatment without compromising accuracy
Fast, Reliable & Highly Accurate Imaging
ExacTrac is an independent room-based system that provides instantaneous X-Ray imaging for detailed target information based on the patient’s internal anatomy. When combined with a proprietary 6D fusion algorithm, it delivers fast and highly accurate patient positioning information.
- Independent room-based system
- Fast, reliable X-Ray image acquisition
- Precise image fusion based on bony anatomy
Automated Patient Positioning
One of the essential requirements of a radiosurgery system is its ability to accurately and efficiently position the patient prior to treatment delivery. ExacTrac offers either 4D or 6D alignment with a range of robotic couches.
- Remote control of couch movement without entering the treatment room
- Improved efficiency of clinical workflows through reduction of overall treatment times*
- Supports a range of 6D robotic couches
Non-Coplanar Verification
Stereotactic radiosurgery involves the planning and subsequent delivery of a highly conformal treatment plan which often entails non-coplanar treatment fields, especially in cranial indications. ExacTrac is uniquely positioned to independently verify the patient’s position at non-coplanar angles due to its room-based architecture, ensuring there are no in-room image verification limitations due to couch or gantry angles.
- Internal verification of the patient’s position
- No imaging limitations due to non-coplanar fields
- No compromise on planning technique due to in-room image verification constraints
