An artificial intelligence (AI)-guided inverse planning system was developed for intensity-modulated radiation therapy (IMRT). This AI system optimizes treatment planning parameters, offering a promising alternative to manual trial-and-error methods.

Area of Science:

  • Medical Physics
  • Artificial Intelligence in Medicine
  • Radiation Oncology

Background:

  • Intensity-modulated radiation therapy (IMRT) requires complex inverse planning to optimize radiation dose distribution.
  • Current IMRT planning often relies on manual, iterative trial-and-error adjustments of objective function parameters.
  • Automating this process can improve efficiency and potentially treatment outcomes.

Purpose of the Study:

  • To develop and evaluate an AI-guided inverse planning system (AIGIPS) for IMRT.
  • To automate the optimization of objective function parameters in IMRT planning.
  • To integrate empirical knowledge using fuzzy logic for improved treatment planning.

Main Methods:

  • Developed an AI-guided system incorporating fuzzy if-then rules to represent inverse planning expertise.

  • Utilized a fuzzy inference system (FIS) to automatically modify weighting factors, dose specifications, and dose prescriptions.
  • Validated the AIGIPS using simulated and clinical IMRT cases.

    • Main Results:

    • The AIGIPS successfully achieved desired dose distributions automatically.
    • The fuzzy inference technique effectively managed complex trade-offs between different planning parameters.
    • The system demonstrated the capability to automate parameter optimization in IMRT.

    Conclusions:

    • The AI-guided inverse planning system (AIGIPS) shows significant promise for automating IMRT.
    • Fuzzy logic integration allows for intelligent optimization of complex treatment planning parameters.
    • AIGIPS offers a potentially superior alternative to traditional trial-and-error IMRT planning approaches.
