Limitations

Simulations are only as good as the models they use; real-world conditions might introduce unexpected variables. The study did not account for all potential sources of error or noise that would be present in a physical setup.

Reliability & validity

Reliability would be assessed by repeating simulations with identical parameters. Validity is addressed by comparing simulation outputs to theoretical predictions or known physics principles, though experimental validation is needed for full clinical validity.

Think critically

To what extent can simulation results be relied upon for critical medical applications without extensive experimental validation? What are the ethical considerations when proposing repurposed technology for patient care?

Design Principles
