Advanced Motion Management for LungTurn motion into context

Discover more

Context brings clarity. In lung cancer radiation therapy, that means bringing moving tumors into visual context for precise treatment. Advanced Motion Management for Lung¹ enables you to identify and contextualize targets, accurately track them with internal anatomy-based intrafraction monitoring and reposition when they shift during SBRT treatment. Smart, integrated software and a proven hardware foundation come together in one streamlined workflow.

Bring tumors
into the light

Elements Motion Analysis evaluates tumor motion and identifies nearby anatomical structures visible on x-rays that move in sync with the tumor. These structures form a Correlation Object, enabling you to put your target into context as you plan and perform SBRT treatments with ExacTrac Dynamic—all without implanting markers.

Treat confidently,
even in challenging cases

The Correlation Object, defined before treatment, enables not only precise intrafraction internal anatomy monitoring, but also a level of confidence you need to treat lung cancer, potentially even in early stages.

React to change,
stay on target

By monitoring breathing, surface and internal anatomy as separate conditions, ExacTrac Dynamic detects shifts during SBRT treatment. Repositioning is based on internal anatomy to keep your treatments on track—a significant extra layer of context.

The key challenge was to precisely correlate respiratory motion with the tumor’s position to visualize it reliably. We can now perform treatments more efficiently without placing additional strain on patients. A major advantage of this technology is that it is non-invasive and has no side effects.²

Motion Analysis and Correlation Object generation

Lay the groundwork with pre-planning

Effective motion analysis starts with robust pre-planning, including image fusion, accurate tumor delineation and AI-based auto segmentation. This foundational step improves workflow efficiency and reduces inter-clinician variability.

Generate and verify the Correlation Object

With pre-planning complete, Elements Motion Analysis evaluates the motion trajectory of all structures within the respective lung lobe relative to the tumor’s motion throughout the breathing cycle and creates a Correlation Object.

The software automatically determines and generates a minimum Correlation Object size required to enable robust patient positioning and monitoring with ExacTrac Dynamic. Comprehensive verification steps then help you validate the generated Correlation Object using intuitive visualization tools.

Lung SBRT with ExacTrac Dynamic

From pre-positioning to repositioning

With ExacTrac Dynamic, the patient is pre-positioned utilizing live surface information, and the set-up is completed with either x-ray positioning utilizing the pre-defined Correlation Object or alternatively with CBCT. This keeps you in control at the critical moment before SBRT for lung cancer begins. ExacTrac Dynamic continuously monitors the patient throughout the beam delivery by combining three crucial modalities in parallel: surface, breathing and the Correlation Object. This enables intrafraction x-ray monitoring and on-the-fly repositioning of the patient in case of a detected internal anatomy shift.

Treatment review and approval

After each SBRT session, the review and approval application provides a complete treatment record: fusions and shifts applied during treatment, ready for physician sign-off. In addition, users can fine-tune their workflow by optimizing x-ray settings for future treatments, or by exploring different Correlation Objects for subsequent sessions.
