In our first transatlantic interview we discuss AI with Dr Martin Willemink, research lead at Stanford Cardiovascular Imaging group. We cover a range of issues related to medical imaging data from de-identification and labelling to synthetic data and federated learning. We discuss the findings of his international survey of radiologists opinions towards AI; and he tells us about his start-up Segmed, how they aim to solve the data problem in AI, and what its like living and working in Silicon Valley.  Special thanks to Merel Huisman and Eusomii for hooking up the interview!
