After On Podcast #21: On Tumors, MRIs, and Telepathy (from Boing Boing)

Mary Lou Jepson was finishing her PhD work in holography at Brown University when she started getting sick. Really sick. After a year of steady decline, she was living in a wheel chair and covered in sores. When she could no longer do simple subtraction in her head, she called it quits. She basically went home to die.

That was when a generous professor sprung for an MRI. It revealed a brain tumor – one which had probably afflicted her more subtly since childhood. Shortly after a successful operation, she was firing on all cylinders. Within six months, she completed her Ph.D. and cofounded her first startup. She has since started two more companies; worked in the top engineering echelons of Intel, Google, and Facebook; served briefly as a professor at MIT; and cofounded the One Laptop Per Child initiative.

Impelled by her searing personal experience, Mary Lou is now honing a technology which, she believes, will revolutionize high-end medical imaging. Accessing this is problematic enough in the US, with its 50 MRI machines per million people. But there are just two machines per million Mexicans, and poorer countries may have just one system in the capital city – if that. And with scans averaging about $2,700, even lavishly-insured Americans might be inadequately monitored. MRIs are more effective than mammograms at detecting certain types of breast cancer, for instance. But expense precludes their use as frontline diagnostics.

Mary Lou believes her technology will be 99.9% cheaper than MRIs (that’s an actual estimate, not a euphemism); radically smaller (the size of a ski cap, not a bedroom); and that its resolution will exceed that of MRIs by a factor of a billion. Yes, that’s an actual “b,” not a typo. And the really cool thing? Her creation might also enable telepathy.

If your mind rebels at the scale of these claims, reread Mary Lou’s credentials, then give my interview with her a listen.
