Radiation Planning Assistant (RPA)
University of Texas, MD Anderson Cancer CenterThe Radiation Planning Assistant (RPA) is a web-based software tool designed to automate and assist in planning radiation therapy for cancers of the head and neck, cervix, breast, and brain metastases. It uses CT images to create contours and treatment plans with photon beam irradiation, improving efficiency and precision in radiotherapy treatment planning. The system generates outlines of organs and tumors and proposes radiation dose plans, which clinicians then review and adjust in their own treatment planning systems before use.
Intended Use
Used to plan radiotherapy treatments for patients with cancers of the head and neck, cervix, breast, and metastases to the brain using external beam photon irradiation and CT images. Creates contours and treatment plans that are imported into the user's own Treatment Planning System for review, editing, and dose recalculation.
Technology
Web-based contouring and radiotherapy treatment planning software that incorporates automated contouring using deep learning algorithms, automated plan optimization using Eclipse Treatment Planning features (e.g., Photon Optimizer, RapidPlan), and quality control checks. Plans are designed for specific cancers involving several anatomic regions and are meant to be imported for final review and dose calculation.
Performance
Performance testing included software verification and validation, multicenter clinical testing on large data sets from multiple anatomical regions and cancers, demonstrating safety and effectiveness comparable to the predicate Eclipse system, with contouring accuracy (DSC > 0.8 for 95% of scans), plan dose conformity within 5-7% of clinical plans, and isocenter localization within 3mm.
