ExacTrac, a fast and highly accurate X-Ray system, provides detailed target visualization and non-coplanar positioning and monitoring for stereotactic cranial radiosurgery treatments
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.
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.
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.
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.
