By partnering with Radformation to implement ClearCalc, the hospital successfully integrated a secondary calculation tool that delivers speed and reliability, ensuring clinical confidence while the patient remains on the treatment couch. **What you’ll learn in this case study:** - How ClearCalc’s speed supports time-sensitive replanning and evaluation - Details on the development of a cryostat correction that uses user-measured input to account for output changes based on gantry angle - The role of the line profile tool in allowing physicists to go beyond point-based comparisons for deeper insight into dose distributions - Results from ten patient cases (prostate and oligomet) demonstrating the agreement between ClearCalc and the treatment planning system for 3D point doses and target structures - How improved structure layering functionality assists in the management of complex MR-guided treatment plans Download the full case study for more. ![](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.
