ExacTrac® provides patient setup calculated in six degrees of freedom. To fully exploit this ability, ExacTrac® Robotic Patient Alignment can correct for rotational uncertainties in pitch, roll and yaw. This ensures patient setup accuracy for stereotactic cranial, head & neck, spine, or IMRT treatments, where tumors are in close proximity to critical structures.

ExacTrac is fully integrated with most treatment couches, allowing not only accurate set-up verification but also automated patient positioning. After precise determination of the required correction shift, ExacTrac interfaces with Varian and Siemens* couches for immediate and fully automatic table motion.

* Interface to Siemens couches via Siemens Delta Motion module


Advanced setup and accuracy with ExacTrac Robotic Patient Alignment

Robotic Couch Capabilities for improved setup accuracy

The ExacTrac Robotic Patient Alignment allows precise patient setup 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 high 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

Patient comfort with Frameless Radiosurgery

Stereotactic sub-millimetric precision with clinical flexibility

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.
