AI End-to-End Radiation Treatment Planning Under One Second
The AI End-to-End Radiation Treatment Planning (AIRT) framework revolutionizes clinical workflows by generating single-arc VMAT prostate plans in under one second. Leveraging deep learning, differentiable dose feedback, and adversarial fluence map shaping, AIRT achieves dosimetric quality comparable to established TPS optimization (RapidPlan Eclipse) while drastically reducing planning time and inter-planner variability. This represents a significant leap towards ultra-fast, standardized, and accessible radiation therapy planning.

Dosimetric Performance vs. Clinical Standards (AcurosXB)
AIRT achieves dosimetric quality comparable to existing clinical standards, ensuring patient safety and treatment efficacy.
| Metric | AIRT (Mean ± SD) | RapidPlan Eclipse (Mean ± SD) | Non-Inferiority (p < 0.05) |
|---|---|---|---|
| PTV Homogeneity Index (HI) | 0.10 ± 0.01 | 0.10 ± 0.01 | ✓ |
| PTV D98 (Gy) | 39.3 ± 0.2 | 39.3 ± 0.2 | ✓ |
| Bladder Dmean (Gy) | 7.7 ± 3.8 | 7.3 ± 3.5 | ✓ |
| Rectum Dmean (Gy) | 5.5 ± 1.4 | 5.4 ± 1.4 | ✓ |
Notes: Data evaluated using Eclipse AcurosXB dose engine for fair comparison. Non-inferiority demonstrated across all tested DVH metrics (Section 3.3, Supplementary Table S3).
Robustness Across Diverse Patient Anatomies
Trained on a vast dataset, AIRT consistently maintains PTV coverage and OAR sparing, adapting effectively to a wide range of patient anatomies.
The Challenge
Traditional RT planning struggles with consistency and adaptability across varied patient anatomies and disease presentations, often requiring extensive manual adjustments and leading to inter-planner variability.
Our Solution
AIRT's deep learning model was trained on over 10,000 intact prostate cases, incorporating data augmentation and a differentiable dose feedback mechanism. This extensive training, combined with adversarial fluence shaping, enables the system to generate high-quality plans robustly across a full spectrum of PTV sizes and anatomical variations.
The Outcome
Demonstrated non-inferiority to clinical plans and consistent PTV coverage and OAR sparing for diverse cases, from minimum to maximum PTV volumes. The system adapts effectively to patient-specific anatomies, ensuring standardized high-quality treatment regardless of case complexity.
