ExacTrac Dynamic for Multiple Brain MetastasesMaster every angle

Discover more

ExacTrac Dynamic for multiple brain metastases ensures submillimetric accuracy for treatments using single-isocenter plans. Swift translational and rotational corrections, especially at non-coplanar couch angles, enable precise dose coverage and small PTV margins while maintaining treatment efficiency.

Save time with single isocenter treatments

Leverage the submillimetric accuracy of ExacTrac Dynamic to treat multiple metastases with a single isocenter. By eliminating the need for separate plans or fractionated treatments, you can achieve faster unified treatment time for multiple brain metastases.

Maintain low margins for all targets

ExacTrac Dynamic enables precise corrections in six degrees of freedom, allowing you to use small margins for all metastases—even those far from the isocenter. This reduces geometric deviations and ensures accurate dose delivery for every target.

Achieve full flexibility in couch angles

As a room-based system, ExacTrac Dynamic offers complete freedom in couch angle selection when planning treatments for multiple brain metastases. Verify internal anatomy at any angle to deliver precise and efficient treatment.

Next-level accuracy in every fraction

Non-coplanar monitoring & correction

ExacTrac Dynamic ensures precise treatment accuracy by frequently verifying patient positioning with fast, low-dose x-ray imaging. The system detects and corrects potential misalignments to ensure precise dose delivery and enhanced patient safety, even during complex treatments at non-coplanar angles.

Dedicated immobilization

The Cranial 4Pi system provides a broad range of immobilization components—from individually adjustable headrests to various non-invasive masks—to address varying patient anatomies and needs. The lightweight fixation system and overlay board simplify daily handling for radiotherapists, while the dose-optimized design reduces attenuation, ensuring precise dose delivery.

Deep linac integration

Integrating seamlessly with leading linear accelerators, ExacTrac Dynamic automates patient plan loading and beam-hold functionality based on preset surface and x-ray tolerances. X-ray acquisitions are automatically triggered by predefined gantry angles or the number of monitor units delivered, enabling efficient and accurate workflows.
