AI Contouring Software for Radiotherapy: Platform Comparison

Radiotherapy departments worldwide have witnessed AI contouring evolve from an experimental tool to an essential clinical technology. For radiotherapy professionals selecting AI contouring software, this decision will shape departmental operations for years ahead. This analysis reviews five premier AI auto-contouring platforms currently delivering meaningful impact in clinical environments. Each solution’s advantages and drawbacks are examined, alongside insights into how these technologies can revolutionize workflows while preserving clinical excellence.

Understanding AI Contouring Software for Radiotherapy

Rather than dedicating hours to manual slice-by-slice contouring, AI software employs deep learning algorithms trained on thousands of expert cases to automatically detect and outline anatomical structures across CT, MRI, and additional imaging modalities.

Modern systems compress contouring time from multiple hours to less than 15 minutes while achieving clinical accuracy that frequently equals or surpasses human performance. These platforms manage anatomical variations and complex cases that traditionally demanded senior physician oversight.

The Case for AI Contouring Software

Most departments face resource constraints. Rising patient volumes combined with staffing challenges create workflow bottlenecks that postpone treatment initiation and exhaust clinical teams.

AI contouring software decreases routine contouring time by 85-97% based on case complexity. Beyond temporal efficiency, it removes inter-observer variability through consistent algorithms founded on established protocols. This creates a multiplier effect, enabling current teams to manage increased caseloads without compromising quality.

Top AI Contouring Platforms

1. Synaptiq

Mediq RT by Synaptiq produces precise contours for most OARs and lymph nodes within 1 minute. The Active Intelligence feature enhances GTV contouring and correction through real-time clinician input integration.

Key Benefits:

• Up to 97.2% time reduction (e.g. H&N cases: 97 minutes → 2.7 minutes)
