Deep learning-based auto-contouring improves consistency and reduces manual effort, but integrating AI tools into established workflows is challenging when platforms differ. This work presents an automated integration of RayStation’s AI-based auto-contouring with the Eclipse treatment planning system (TPS) .  \nMaterials and methods: Custom scripts were developed in Eclipse (C\\#) and RayStation (Python), supported by DICOM networking, to enable automated data exchange. The Eclipse script exports computed tomography (CT) images and a list of requested structures to RayStation. Upon receipt, RayStation 2024B automatically triggers a Python script that performs deep learning segmentation using built-in models. The resulting contours are then exported back to Eclipse for review, requiring no user interaction beyond initial input.  \nResults: The integration was validated on 35 clinical cases. The complete process, from CT export to contour availability in Eclipse, averaged 1.1 minutes per case. The solution significantly reduces contouring time and improves workflow consistency. Conclusion: This automated cross-platform integration enables deep learning segmentation from RayStation to be accessed directly within Eclipse, offering a streamlined and scalable contouring solution. It enhances planning efficiency, reduces inter-observer variability, and allows clinicians to benefit from state-of-the-art AI tools within their existing TPS. The framework is modular and adaptable to evolving clinical protocols, serving as a practical example of multi-vendor system interoperability in modern radiotherapy planning.  \nKeywords: deep learning auto-contouring; radiotherapy treatment planning; RayStation — Eclipse integration; artificial intelligence in radiation oncology; DICOM automation  \nRep Pract Oncol Radiother 2025;30(6):749–757  \nIntroduction  \nAccurate delineation of target volumes and organs-at-risk (OARs) is a critical yet time-consuming step in radiotherapy treatment planning. Manual contouring by clinicians can delay planning  \nand introduce inter-observer variability [1–3] . Traditional auto-contouring approaches, such as atlas-based segmentation, have been used to alleviate this burden by propagating contours from reference atlases [4] .
