Tiny rotating probe delivers 360-degree optical coherence tomography scans inside brain arteries

Researchers have developed a tiny optical imaging probe designed for optical coherence tomography (OCT) inside blood vessels in the brain. With further development, the tiny probe—which is about the width of a pencil lead and the length of a grain of rice—could be used to acquire detailed information about vascular disease and devices such as stents implanted in the brain.
