Summary
Machine learning (ML) in radiation oncology faces challenges due to data-model dependency and low interpretability. Addressing these is crucial for reliable clinical implementation and risk assessment of ML tools.
Area of Science:
- Medical Imaging
- Artificial Intelligence
- Radiation Oncology
Background:
- Machine learning (ML) adoption is increasing in medicine, particularly in radiation oncology, leveraging advancements in deep learning and data availability.
- Radiation oncology has a history of digital workflows, making it receptive to ML integration.
- ML models, unlike traditional ones, are complex and data-dependent, raising concerns about performance and transparency.
Purpose of the Study:
- To review the risks and solutions for applying ML in radiation oncology workflows.
- To define and illustrate core concepts of interpretability, explainability, and data-model dependency in ML.
- To discuss ML applications and vendor perspectives for clinical integration.
Main Methods:
- Review of current literature on ML risks and solutions in radiation oncology.
- Formal definition and exemplification of interpretability, explainability, and data-model dependency.
- Discussion of ML applications and vendor viewpoints.
Main Results:
- ML implementation in radiation oncology is hindered by data-model dependency and lack of interpretability.
- Understanding and mitigating risks related to data and model interactions is essential.
- Key ML applications and vendor considerations for clinical use are explored.
Conclusions:
- Developing robust ML tools for radiation oncology requires addressing interpretability and data-model dependency.
