Synthesis: Xu et al. (2026) present an agentic AI-driven immersive simulation for training in High Dose Rate (HDR) brachytherapy, integrating VR and mobile computing to create a high-fidelity, risk-free environment for mastering complex procedural skills. A knowledge-aware assistant uses Retrieval-Augmented Generation to ground agent interactions in authoritative clinical guidelines, providing natural-language interfaces and hands-free, real-time guidance during intricate maneuvers. A prototype on Meta Quest 3 with a local GPU-backed AI backend demonstrated feasible architecture with suitable latency and high context precision, answer completeness, and relevance. The work connects to Simulation, Professional Training, and Professional Training research.

Immersive, Risk-Free Clinical Training

The convergence of the Metaverse and LLM-based AI agents is catalyzing a shift toward autonomous, immersive, and personalized pedagogical frameworks in medical education. This system targets HDR vaginal cylinder brachytherapy in cancer care, integrating VR and mobile computing to let trainees master complex procedural skills without the facility or safety constraints of physical anatomy or live radioactive sources.

RAG-Grounded Knowledge Assistance

A core contribution is the seamless integration of a knowledge-aware assistant leveraging Retrieval-Augmented Generation to ground agent interactions in authoritative clinical guidelines. This enables an interactive agent to provide natural-language interfaces and hands-free, real-time guidance during intricate medical maneuvers.

Validation

A prototype deployment comprising a Meta Quest 3 interface linked to a local GPU-accelerated AI backend demonstrated a feasible architecture, maintaining suitable end-to-end latency and high context precision, answer completeness, and relevance in the RAG-enhanced pedagogical support.
