This is your brain's blood vessels on drugs
Date:8/28/2014

, the part of the vessel that's perpendicular to the line of sight wouldn't be visible, instead appearing dark. But by tracking the blood vessel as it slopes up or down near this dark spot, the researchers developed a way to use that information to interpolate the missing data more accurately.

ODT can only see down to 1-1.5 millimeters below the surface, so the method is limited to smaller animals if researchers want to probe into deeper parts of the brain. But, Pan says, it would still be useful when the brain's exposed in the operating room, to help surgeons operate on tumors, for example.

The new method is best suited to look at small blood vessels and networks, so it can be used to image the capillaries in the eye as well. Bioengineers can also use it to monitor the growth of new blood vessels when engineering tissue, Pan said. Additionally, information about blood flow in the brain could also be applied to developing new treatment options for recovering drug addicts.
