AutoContour was known for its efficient workflows for reviewing contours and its registration workspace, while Limbus Contour excelled at its Zero-Click workflow. Both solutions offered a large library of models, and when planning the merged product, the teams were committed to releasing contours validated against written guidelines and clinical standards. In this new merged version, AutoContour v2.7, 480 AI-trained models are available to offer users the best AI contours in radiation oncology. Some models originated from Limbus Contour, others from AutoContour, and the remaining were newly updated or released in this version.   ![](https://resources.radformation.com/hubfs/raw_assets/public/@marketplace/kalungicom/atlas-theme/images/Dashboard.svg) [![Radformation](https://resources.radformation.com/hubfs/Radformation_Logo_Pen%20(1).png)](https://radformation.com/) 261 Madison Avenue 9th Floor New York, NY 10016 1-844-RADFOR5 (7233675) ### PRODUCT - [AutoContour](https://radformation.com/autocontour/autocontour) - [EZFluence](https://radformation.com/ezfluence/ezfluence) - [OptiPlan](https://radformation.com/optiplan/optiplan) - [ClearCheck](https://radformation.com/clearcheck/clearcheck) - [ClearCalc](https://radformation.com/clearcalc/clearcalc) - [RadMonteCarlo](https://radformation.com/radmontecarlo/radmontecarlo) - [ChartCheck](https://radformation.com/chartcheck/chartcheck) - [ChartCheck Adaptive](https://radformation.com/chartcheck/adaptive) - [RadMachine](https://radformation.com/radmachine/radmachine) - [QuickCode](https://radformation.com/quickcode/quickcode) ### RESOURCES - [Blog](https://blog.radformation.com/?hsLang=en) - [Case Studies](https://resources.radformation.com/case-studies?hsLang=en) - [Webinars](https://resources.radformation.com/webinars?hsLang=en) - [White Papers](https://resources.radformation.com/white-papers?hsLang=en) - [Videos](https://resources.radformation.com/videos?hsLang=en) - [Surveys](https://radformation.com/surveys) - [Privacy Settings](https://radformation.com/privacy-settings) ### CALCULATORS - [BED Calculator](https://radformation.com/tools/bed-calculator) - [Decay Calculator](https://radformation.com/tools/decay-calculator) - [Interpolation Calculator](https://radformation.com/tools/interpolation-calculator) ### COMPANY - [About](https://radformation.com/about) - [Careers](https://radformation.com/careers) - [Contact](https://radformation.com/contact) - [Events](https://events.radformation.com/?hsLang=en) - [Sales](https://radformation.com/contact/sales) - [Support](https://radformation.com/success-support) - [Research](https://info.radformation.com/research?hsLang=en) - [Press](https://radformation.com/press) - [Policies](https://radformation.com/privacy-policy) © 2026 Radformation, Inc.
