New Technology Gives Unprecedented Look Inside Capillaries

Now a Northwestern University team has developed a new tool that images blood flow through these tiny vessels, giving insight into this central portion of the human circulatory system. Called spectral contrast optical coherence tomography angiography (SC-OCTA), the 3-D-imaging technique can detect subtle changes in capillary organization for early diagnosis of disease. "There has been a progressive push to image smaller and smaller blood vessels and provide more comprehensive, functional i...
