What is the RPA?
The Radiation Planning Assistant provides a suite of fully automated contouring and radiotherapy planning tools designed to deliver consistent, high-quality treatment planning.
The workflow begins with the user uploading a CT scan and completing a Service Request form, after which the planning process is initiated automatically. Patient data are securely transferred, de-identified, and processed within the RPA system to ensure both privacy and reliability.
For complex treatments, such as VMAT planning for head and neck cancers, the system performs automated contouring that is reviewed and edited by the user within their local treatment planning system before being returned to the RPA for final plan generation. For simpler treatments, such as 4-field box plans for cervical cancer, the system can generate a complete plan with minimal user interaction.
In all cases, the final plan is returned to the user’s treatment planning system for dose recalculation, review, and any necessary modification prior to clinical use. The RPA is intended to enhance clinical workflows while maintaining full clinician oversight; final plan evaluation and quality assurance remain the responsibility of the treating institution.
