ExacTrac Dynamic Implanted Marker WorkflowIn motion,
on point

Enhance soft tissue localization with ExacTrac Dynamic, which automatically detects implanted markers during both positioning and monitoring phases of treatment. This detection occurs in 6DoF, allowing for precise shifts that can be sent to the treatment couch to actively manage the motion of the moving target during SBRT prostate cancer treatments.

Customize your workflow with flexible imaging options. Use cone beam CT (CBCT) positioning to assess filling of the bladder and rectum before beam delivery for safe, reproducible and accurate treatment. Alternatively, opt for positioning based on x-rays for minimal imaging dose. No matter your positioning choice, the monitoring is always conducted by x-ray imaging, crucial for prostate SBRT.

Ensure precise irradiation of the target tissue with the automatic beam hold function. Frequent imaging of internal anatomy and real-time monitoring of the thermal surface in 6DoF detect significant deviations from preset tolerances, triggering an instant beam hold. Automated x-ray imaging at small intervals allows for frequent fiducial marker detection, helping to minimize the risk of irradiating healthy tissue. 

Benefit from the integration of augmented surface guided radiation therapy (SGRT) and image guided radiation therapy (IGRT) for enhanced tracking. The system utilizes three imaging modalities throughout the treatment steps: live surface matching with CT outer contour during pre-positioning; thermal signature capture at each fraction to enable tracking of small, flat areas with limited topological information; and x-ray imaging for accurate positioning. Finally, monitoring combines thermal-surface and x-ray tracking to support accurate treatment delivery.
