To develop an interactive dosimetric scorecard interface that would be based on standardized and contextualized clinical goals. The clinical goals would need to be easily modifiable and automatically selected based on clinical context.

Our scorecard interface was integrated into our in-house software (LINK) that runs within RayStation (RS). LINK fetches data from a second in-house software called CDe where the clinical and technical contexts are stored and paired. LINK aligns all the required steps to generate a treatment plan. Our scorecard interface uses data within the clinical context for plan analysis and to display the result.
The data contains standardized clinical goals defined within CDe by an interdisciplinary group of clinicians. For each target and organs at risk (OAR), minor and major deviations were defined for each dose prescription as standard in the database.
The scorecard interface queries RS for specific DVH values defined in the standards and displays the results with a traffic light color scheme representing minor or major deviations from the defined tolerances.

Our scorecard interface provides multiple benefits. First, it is interactive in the sense that the clinical context is automatically updated depending on what patient, plan and dose is being planned. That creates a quick and smooth planning experience for the clinicians with minimal interactions. Second, the clinical standards are defined outside of our TPS in a secure database. And since each clinical goal is entered only once, it minimizes the risk of errors. Finally, with the scorecard interface it is possible to incorporate minor and major deviations and display the results in a meaningful way.

We developed an interactive dosimetric evaluation scorecard based on an independent database allowing a simplified management of the standards and a customized display resulting in a more adapted and effective analysis of a radiotherapy plan.
