Positioning & Target Control

Intrafractional Verification

ExacTrac Dynamic delivers high-precision treatments for a wide range of patient positioning and monitoring workflows including cranial and prostate. This all-in-one system’s revolutionary new thermal-surface camera technology works in tandem with real-time X-Ray tracking for submillimetric accuracy.

Exactrac Dynamic - Radiation Oncology Monitoring System Overview
Cranial 4Pi Immobilization Device with SRS Mask

Cranial 4Pi Immobilization System

The ExacTrac Dynamic 4Pi Immobilization 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

X-Ray Verification Treatment and Positioning

Fast, Reliable & Highly Accurate Imaging 

ExacTrac Dynamic 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
ExacTrac allows for remote control of couch movements improving radiotherapy treatment efficiency

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 Dynamic 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
Treatment Cranial

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 Dynamic 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
