As a pathology resident, this is the kind of thing that makes me wonder if I should be looking for a new job. But everything radiology does is digital, and they haven't run out of radiology jobs, so maybe the future's not so bad...
Medical equipment manufacturers might have more to worry about, but I'd guess the amount of regulation involved will probably buffer them long enough to adapt to any changes.
What's most fascinating to me about Ozcan's work is the amount of computational photography involved for getting usable images. A few years back it was mostly MATLAB but I imagine now you could write shaders that run right in the phone GPUs...
Hopefully CAD tools will speed you up, rather than put you of a job. Having worked with pathologists, I think digital has a ways to go before it replaces you entirely.
