Objective:

To develop a treatment planning support infrastructure that utilizes comprehensive geometric anatomical models for knowledge-based treatment planning (KBP) in radiotherapy, enhancing precision and effectiveness.

Key Findings:
  • The infrastructure enables the calculation of quantitative features between GTV and OARs, facilitating a holistic representation of their geometric relationships, which can lead to more tailored treatment plans.
  • The system allows for equivalent comparison of cases despite anatomical variations by normalizing similarity scores based on common OARs, thus improving the reliability of predictions.
  • Identifying cases by GTV-OAR constellation geometry can lead to improved dose-volume histogram (DVH) predictions, potentially enhancing treatment efficacy.
Interpretation:

The proposed KBP infrastructure enhances the treatment planning process by utilizing geometric relationships between target volumes and surrounding organs, potentially leading to better treatment outcomes and reduced side effects.

Limitations:
  • The system's effectiveness depends on the quality and comprehensiveness of the retrospective case datasets used, which can vary significantly across institutions.
  • Further validation is required to assess the clinical impact of the proposed decision support system, particularly in diverse patient populations.
Conclusion:

The development of a knowledge-based treatment planning infrastructure represents a significant advancement in radiotherapy, aiming to optimize treatment plans while minimizing risks to healthy tissues, ultimately improving patient outcomes.
