Real-time volumetric optical coherence tomography OCT imaging with a surgical microscope

SpringerLink Home Feb 19 2011 Microscopy , Otolaryngology

Optical coherence tomography is a unique technique to visualize subsurface tissue structures with a resolution below 10μm during microsurgery without tissue contact. Since it was introduced more than 15 years ago imaging speed was boosted by more than three orders of magnitude, from less than 100 to more than 300,000 A-scans per second. Instead of taking only still images of anatomical structures, the increased speed of OCT allows now to image volumes nearly in real time. This enables not only the scanning of larger tissue surfaces, but also opens new application beyond simple diagnosis. A noncontact volumetric imaging with ...
