Review Questions

• How does artificial intelligence enhance the personalization of radiotherapy treatments?
  • Artificial intelligence enhances personalization by analyzing patient-specific data, including imaging results and genetic information. This allows AI systems to identify unique tumor characteristics and predict how a patient might respond to different radiation doses. By tailoring treatment plans based on these insights, oncologists can improve efficacy while minimizing side effects, ultimately leading to better patient outcomes.
• Evaluate the impact of machine learning on optimizing radiation dose delivery in radiotherapy.
  • Machine learning significantly impacts the optimization of radiation dose delivery by analyzing large datasets to identify patterns that inform dose calculations. These algorithms can predict how different dose distributions will affect both tumor control and healthy tissue preservation. This leads to more accurate dose prescriptions, reducing the risk of over-treatment or under-treatment while maximizing therapeutic effects.
• Assess the potential ethical considerations arising from the use of artificial intelligence in radiotherapy.
  • The use of artificial intelligence in radiotherapy raises several ethical considerations, such as data privacy, consent, and bias in algorithm development. Patient data used for training AI must be handled securely to maintain confidentiality. Furthermore, if algorithms are trained predominantly on data from specific demographics, they may not perform equally well across diverse populations. Addressing these issues is crucial for ensuring equitable access to personalized treatment and maintaining trust between patients and healthcare providers.
