    3. Feature Of The Week 2/13/09: Common-Path Optical Coherence Tomography Using an Integrated Fiber Microlens

      Feature Of The Week 2/13/09: Common-Path Optical Coherence Tomography Using an Integrated Fiber Microlens
      Feature Of The Week 2/13/09: Common-path optical coherence tomography systems have a variety of advantages over traditional interferometer implementations in certain applications. These include compactness, stability, tolerance to group velocity dispersion, and polarization missmatch since the sample arm and reference arm, to a high degree, share the same path. A recent paper by Khay Ming Tan et al from the University of St. Andrews demonstrates this in a Fourier-Domain OCT system where they integrate the reference reflection and a fiber micro-lens and discuss applications such as needle biopsy and endoscopy.

      Feature Of The Week 2/8/09: Application of Optical Coherence Tomography to Deep Lamellar Endothelial Keratoplasty (DLEK) Procedures
      Feature Of The Week 2/8/09: OCT has had a dramatic impact on ophthalmology over the past 20 years. Evolving from a scientific concept to a main stream imaging and diagnostic tool used world wide. Next generation Fourier domain systems are now commercialized and offering major advances such as 3D data sets and functional imaging in acquisition times and resolutions that yesterday's 2D system could not achieve. Improved imaging is synergistic with new surgical techniques. For example, laser vision correction has become one of the fastest-growing disciplines in medicine. A fairly new corneal transplant procedure called deep lamellar ...

      Feature Of The Week 1/31/09: Polarization-Sensitive Optical Coherence Tomography Imaging of Demineralization on Tooth Surfaces
      Feature Of The Week 1/31/09: The promise of low-cost, high-resolution, non-ionizing imaging for dentistry continues to spur research and commercial activity. Daniel Fried, a professor from UCSF, has done a lot of interesting work on OCT applications in dentistry. One recent publication shows PS-OCT imaging of demineralization of tooth roots. This figure contains three images: Top/A Polarized Light Microscopy (PLM), Center/B microradiography (TMR); and bottom/C PS-OCT. The PS-OCT B-scan image is of the orthogonal polarization state, taken across a block of human dentin after exposure of the block to a solution designed to cause subsurface ...

    6. Feature Of The Week 1/25/09: Fourier Domain a Hugh Boost to Optical Coherence Tomography for Cardiovascular Applications

      Feature Of The Week 1/25/09: Fourier Domain a Hugh Boost to Optical Coherence Tomography for Cardiovascular Applications
      Feature Of The Week 1/25/09: By the early 1990's both Ophthalmology and Cardiology were being investigated as potential applications of OCT (see for example Huang et al). But while OCT for ophthalmologic exams developed into a main stream application in less than 10 years with well over 10,000 units currently fielded, 100,000’s patients diagnosed, and over $200M/year in revenue for a variety of Companies, cardiology has lagged behind. This is due to a variety of issues including the more invasive and complex nature of the procedure and the implicit demand on the technology ...
