Jonathan Rothberg's chip that could disrupt medical imaging

Not sure whether it's bravado and whether Rothberg can deliver, but given his track record, this is something to watch which could also significantly reduce the cost of healthcare (Wired):

Rothberg says he has raised $100 million to create a medical imaging device that’s nearly “as cheap as a stethoscope” and will “make doctors 100 times as effective.” The technology, which according to patent documents relies on a new kind of ultrasound chip, could eventually lead to new ways to destroy cancer cells with heat, or deliver information to brain cells.

[...]Rothberg says he got interested in ultrasound technology because his oldest daughter, now a college student, has tuberous sclerosis. It is a disease that causes seizures and dangerous cysts to grow in the kidneys. In 2011 he underwrote an effort in Cincinnati to test whether high-intensity ultrasound pulses could destroy the kidney tumors by heating them.

What he saw led Rothberg to conclude there was room for improvement. The setup—an MRI machine to see the tumors, and an ultrasound probe to heat them—cost millions of dollars, but wasn’t particularly fast, more like a “laser printer that takes eight days to print and looks like my kids drew it in crayon,” he says. “I set out to make a super-low-cost version of this $6 million machine, to make it 1,000 times cheaper, 1,000 times faster, and a hundred times more precise.”
