Researchers have developed a camera-like imaging device that can be inserted into blood vessels to provide high-quality 3D images to help scientists better understand the causes of heart attack and heart disease progression and could lead to improved treatment and prevention.

The team was able to 3D print a tiny lens onto the end of an optical fiber that is the thickness of a human hair. The imaging device is so small that researchers were able to scan inside the blood vessels of mice.

What do you think: Will inserting lenses inside blood vessels become a practical tool for diagnosing disease?
