(via Tiny Probe Will Swim Through Arteries to Provide 3D Images | Gadgets, Science & Technology)
Clearing clogged arteries usually involves complicated and dangerous surgery. Even looking at the arteries involves complex cross-sectional ultrasounds which only allow a view from outside of the arteries. Thanks to a team at the Georgia Institute of Technology, this tiny probe could give a clearer look at clogged arteries by actually going inside them. A single computer chip measuring just 1.4 millimeters wide holds over a hundred elements that transmit data to doctors via 13 minuscule cables.
