In this episode, Stephen and Dr. Chee sit down with Dr. Lee Walsh, former Digital Health Lead at the TGA and current head of Platypus MedTech Consulting. Together, they pull back the curtain on the complex, fast-moving, and often misunderstood world of health AI regulation.  

From the high-stakes environment of radiology to the quiet explosion of consumer-facing chatbots like ChatGPT, Dr. Walsh breaks down how regulators evaluate safety, why the current system is actually more flexible than you think, and the terrifying reality of what happens when free, unvetted AI undercuts evidence-based medical technology. 

If you are a clinician, technologist, or patient wondering who is actually keeping the safety net intact as medicine digitizes, this conversation is an absolute must-watch.  

What You Will Learn:

The Blueprint of Innovation:  How the medical device framework is built on principles rather than strict prohibitions, forcing inventors to define safety standards from first principles.  

The Radiology Legacy: Why medical imaging holds a unique, highly protected regulatory status due to its history with radiation and definitive diagnostic power.  

Locked Models vs. Generative Chaos: The staggering regulatory difference between purpose-built machine learning models and general-use LLMs that can hallucinate or change day-to-day.  

The Commercial Death Loop: Why rigorous, evidence-based clinical AI tools are struggling to compete against free, unregulated consumer chatbots.  

The Actionable Framework for Practice Owners: How to implement ISO 42001 or use a first-principles failure mindset to aggressively vet AI vendors, protect data privacy, and establish clear escalation pathways
