    7. Feature Of The Week 9/11/11: Researchers at University of Florida Probe Into Miniature MEMs for OCT Imaging

      Feature Of The Week 9/11/11: Researchers at University of Florida Probe Into Miniature MEMs for OCT Imaging
      Researchers at the University of Florida, let by Dr. Huikai Xie, have been active for many years in developing advanced optical scanning technology using MEMS technology. Such technology is important for OCT and other optical imaging modalities. Below is a summary of some of their recent work.Endoscopic optical coherence tomography (OCT) imaging is very useful since it can replace risky, painful and time-consuming biopsy. However Endoscopic OCT is also ...
