    2. Optical Coherence Tomography Industry Has Provided Well Over 20,000 Person-Years of Direct Employment

      Optical Coherence Tomography Industry Has Provided Well Over 20,000 Person-Years of Direct Employment
      The field of Optical Coherence Tomography (OCT) has grown dramatically since its discovery in the early 1990s. The commercialization and growth of OCT which has occurred over the past 25 years has been highly impactful, scientifically, clinically, and economically. Many factors have helped drive this success starting with the clinical need for new cost-effective high-resolution minimally-invasive imaging solutions for various diagnostic and therapeutic applications. But equally important to this success ...
