When looking to examine the heart and blood vessels, the images scientists get from techniques like cross-sectional ultrasounds can provide limited information.
"If you're a doctor, you want to see what is going on inside the arteries and inside the heart, but most of the devices being used for this today provide only cross-sectional images," explained F. Levent Degertekin, a professor in the George W. Woodruff School of Mechanical Engineering at Georgia Tech. "If you have an artery that is totally blocked, for example, you need a system that tells you what's in front of you. You need to see the front, back, and sidewalls altogether."
Such a system may now be on the horizon, thanks to Degertekin and a team of researchers at Georgia Tech. They've developed a minuscule sensor that could travel through the bloodstream to send highly detailed 3D images back to an external sensor. … Read more
