Achieve submillimetric radiotherapy positioning & monitoring accuracy
Achieve submillimetric radiotherapy positioning & monitoring accuracy
ExacTrac Dynamic unifies the power and precision of cutting-edge tracking technologies. Deliver 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 extraordinary accuracy.
Merging surface & X-Ray tracking
Thermal surface tracking
The 4D Thermal Camera creates a highly accurate and reliable hybrid thermal surface by correlating the patient’s heat signature to their reconstructed 3D surface structure. To achieve this, 300,000 3D surface points are acquired and matched to the heat signal generated by the thermal camera, creating another dimension to track their position.
Advanced X-Ray monitoring*
Larger panels show more anatomy for easier orientation and interpretation of X-Ray images. At the same time, improved soft tissue contrast and enhanced read-out speed prevent motion blurring effects. Thanks to higher heat capacity, ExacTrac Dynamic X-Ray tubes support more automated, high frequency imaging.
Integration for greater automation*
Deep integration with Elekta Versa HD™ in combination with Hexapod™ and Varian Edge™ or TrueBeam™ with Perfect Pitch™ enable automated beam hold—repositioning and restarting treatment—from the linac console. Based on the indication, protocol or patient, X-Rays can be automatically or manually triggered for greater freedom.
Flat Panel Detectors*
This new imaging hardware has been specifically designed to address the challenges associated with motion management-
- Increased field size at the isocenter(18 x 18cm) for better orientation
- Prevents motion blurring effects across the panel for moving targets
- High Definition Structured Light Projector (300,000 3D data points)
- Stereoscopic Low Latency Data Cameras (20 frames per second)
- Integrated Thermal Camera
4D Thermal Camera
The new 4D Thermal Camera adds a fourth dimension by combining 3D surface with thermal imaging, creating a one-of-a-kind hybrid thermal-surface to enable highly accurate tracking.
Key advantages
- Submillimetric accuracy
- Consistent tracking of very large (645mm x 490mm) and very small (sternum) areas of interest
- Simplified area of interest selection
- No gantry related camera blocking

Cranial 4Pi Immobilization
Completely revamped, ExacTrac Dynamic immobilization is now a straightforward, all-in-one solution. The new dose optimized and user-friendly design is compatible with several available couch tops.
Allows for easy mounting and removal of masks as well as simple adjustment of mask space in the case of weight loss or edema.
Created for high accuracy SRS treatments, this mask consists of two anterior sheets, a custom nose bridge and a patient-specific posterior mask.
Ideal for claustrophobic patients or surface tracking for cranial indications, this mask features a single open-faced anterior sheet and a patient-specific posterior mask.
Designed for treatments requiring less accuracy (WBRT, palliative), this mask consists of a single closed-faced anterior sheet and a comfortable carbon base head rest.
Software
Function-focused user interface
The customizable, user-centric user interface brings function to the forefront. Automated workflows with preset indication-specific templates drive standardization of treatments throughout the department or even across multiple locations.
Advanced image fusion*
Larger and higher quality X-Rays are matched on the software side with extended DRRs for better visualization of and easier orientation within the patient anatomy. Convenient fusion tools such as the rubber band snap back fusion functionality further simplify the verification process.
Deep linac integration
Deep integration with high-end linear accelerators enables not only automated patient loading but also automated beam-hold based on preset surface and X-Ray tolerances. The same deep level of integration allows for the automated triggering of X-Rays based on predefined gantry angles or MU intervals.
Non-coplanar monitoring
ExacTrac Dynamic continuously verifies the patient’s initial position with X-Ray imaging throughout treatment delivery. Even at non-coplanar couch angles and during beam-on, the system can detect potential patient misalignment helping to mitigate treatment errors.
Workflows
Multiple indications — one ExacTrac Dynamic
ExacTrac Dynamic addresses a wide range of clinical challenges and treats indications that previously required multiple systems. Submillimetric surface-thermal and X-Ray tracking enable PTV margin reduction, providing true dose sparing for critical structures.
