Learn how to build applications with the Varian ARIA API using practical C# examples. This article covers bearer token authentication, HttpClient configuration, FHIR resource lookups, reusable helper methods, pagination, and JSON parsing—providing the essential programming patterns needed to develop robust clinical automation tools that integrate with the ARIA API.

In this second installment of the ARIA API series, we explore the ARIA API Specifications Page and API Tester. Learn how to navigate FHIR profiles, operations, search parameters, radiotherapy resources, ValueSets, and real-world examples while discovering practical techniques for exploring and validating ARIA API workflows before writing code.

Explore the foundations of the Varian ARIA API and modern healthcare interoperability in radiation oncology. This introduction reviews HL7 FHIR concepts, ARIA API architecture, VAIS configuration, API client setup, and basic API testing while demonstrating how modern APIs can support clinical automation, workflow tools, reporting, and integration across oncology systems.

Building on our automated planning series, this post explores how to capture Eclipse optimization and dose calculation output in real time. By leveraging a custom TraceListener, we transform internal ESAPI feedback into actionable UI updates—enabling detailed progress tracking, multiple progress bars, and richer user feedback during long-running planning workflows.

Learn how to build Script Approval Extensions in ESAPI 18.1 to automate plan checks during Eclipse approval. This step-by-step example validates heterogeneity correction and prescription accuracy, demonstrating how approval extensions improve safety, consistency, and automation in radiation therapy planning.

In Part III of our Automated Planning from Templates series, we tackle ESAPI UI freezing with a multi-threaded worker pattern, ensure thread-safe updates, and add a progress bar for real-time feedback. The result: smoother, safer, and more responsive automated planning applications.

Learn how to automate RapidPlan optimization in Eclipse using the Clinical Template Reader API. This follow-up blog shows how to apply a RapidPlan model to a template-based plan, calculate dose, and evaluate protocol-based metrics—all within a custom MVVM application.

Learn how to automate treatment planning in Eclipse using the Clinical Template Reader and ESAPI. This blog revisits the Clinical Template Driven Plan Automation webinar, guiding you through setting up a clinical protocol and building a simple automated planning UI to generate plans directly from templates. Start your journey toward efficient, standardized planning workflows.
