The Siemens Healthineers business area Varian announced today that AI contouring capabilities for use with the Eclipse treatment planning system have received CE mark, representing an important step in the use of artificial intelligence to support radiation therapy planning. Seamlessly integrated into the clinical workflow with the Eclipse treatment planning system, the AI contouring device provides automatic contouring of more than 200 pre-defined structures based on CT and MR images, including organs of interest, lymph nodes, and known (diagnosed) brain metastases. The solution offers clinicians a standardized, high-quality starting point for review and refinement, with the aim of improving efficiency and contour consistency while preserving clinical oversight of treatment planning decisions.
