Powered by Oncospace, now part of Sun Nuclear, Plan AI helps radiation oncology teams save time and drive improvements in plan quality with predictive, patient-specific insights on achievable goals before planning begins.
The Quality You Expect. Faster. Easier.
Plan AI is a data-driven, AI-powered, cloud-native software application that predicts the ‘Best Achievable’ radiation therapy treatment plan outcomes upfront – before planning begins. By surfacing what’s clinically possible early, Plan AI supports your team’s goals of planning smarter, faster, and more collaboratively.
Plan AI enables radiation oncology teams to:
- Improve planning efficiency by reducing iterations and manual revisions
- Engage physicians early with predictive insights that support decision-making
- Accelerate plan approval by aligning teams around data-driven expectations
- Balance quality and deliverability from the start, with less trial and error
- Standardize care across teams
“Plan AI provides confidence that each plan is being driven towards a good result for the patient. It will mean we spend less time adjusting the planning goals and waiting to see the effect on the dose distribution.”
Radiation Oncologist, University of Virginia

Unlike traditional TPS add-ons, Plan AI is not a checker, optimizer, or contouring tool. Rather, it’s a clinical guide to the improved plan outcomes for your patients.
- Create personalized clinical goals and planning strategy before planning with DVH Predictions* of OAR sparing
- Import ‘Best Achievable’ dosimetric objectives into the TPS to drive plan creation
- Peer review all plans with communication tools and structured checklist
Data-Driven. AI-Powered.
With robust models based on 5,000+ clinically delivered plans from Johns Hopkins University,
you can count on proven quality for each treatment site – resulting in significantly less optimization effort required.
Plan AI supports:
- DVH predictions for OAR sparing before planning begins, enabling comparison to clinical goals and TPS outputs
- DVH evaluation allows at-a-glance comparison of predicted dose if available, clinical goals, and plan results with a DVH display and scorecard
- 50+ prescription and geometry features, supporting a wide variety of protocols
- Peer review using structured checklists, customizable clinical goal templates, and comparisons of TPS results to goals and predictions
- CT Image + Plan viewer for navigation and inspection of CT images, structures, and dose distribution
- Comprehensive, collaborative protocol management and plan evaluation tools are provided, including a Course Protocol Library that can be used as-is, modified, or form the basis for new protocols
Plan AI software for prostate and head and neck, thoracic, abdomen, and pelvis radiotherapy is FDA 510(k) cleared, and for sale in the United States only.
Oncospace is now part of Sun Nuclear and the Mirion Medical family.
