      MIT team takes high-res, 3-D images of eye
      In work that could improve diagnoses of many eye diseases, MIT researchers have developed a new type of laser for taking high-resolution, 3-D images of the retina, the part of the eye that converts light to electrical signals that travel to the brain. The research will be presented at the Conference on Lasers and Electro-Optics and the Quantum Electronics and Laser Science Conference in Baltimore on May 10.

    3. Holographic imaging spectrometer

      A holographic imaging spectrometer, apparatus, and/or method enables the projection of a two-dimensional (2D) slice (having spectral information) of a four-dimensional (4D) probing object. A 4D probing source object is illuminated to emit an optical field. A holographic element having one or more recorded holograms receives and diffracts the optical field into a diffracted plane beam having spectral information. Collector optics (e.g., an imaging lens) focuses the diffracted ...

    5. High-resolution imaging of progressive articular cartilage degeneration

      High-resolution imaging of progressive articular cartilage degeneration
      The objective of this study was to develop and verify a new technique for monitoring the progression of osteoarthritis (OA) by combining a rat model with the imaging modality optical coherence tomography (OCT). Time-sequential, in vivo, OCT imaging was performed on the left femoral condyles of 12 Wistar rats following sodium-iodoacetic acid-induced OA progression. The right femoral condyles (untreated) were also imaged and served as controls. Imaging was performed on ...

    6. Enhanced visualization of retinal pathologies with ultrahigh resolution optical coherence tomography (Thesis)

      Enhanced visualization of retinal pathologies with ultrahigh resolution optical coherence tomography (Thesis)
      Current clinical practice calls for the development of techniques to diagnose diseases in its early stages, when treatment is most effective and significant irreversible damage can either be prevented or delayed. Optical coherence tomography (OCT) is an emerging medical diagnostic technology being investigated for applications in a number of medical fields including ophthalmology, cardiology, and gastroenterology. OCT is analogous to ultrasound except that it uses light waves rather than sound ...

    8. Methods and systems using field-based light scattering spectroscopy

      The present invention relates to systems and methods of field-based light scattering spectroscopy. These systems and methods provide for the diagnosis of tissue by measuring the size and distribution of cellular characteristics. Field based measurements provide phase information resulting from the interaction of scatterers within the material and the incident wavefront. These measurements can be used to provide three dimensional images of tissue.

      Real-time, ultrahigh-resolution, optical coherence tomography with an all-fiber, femtosecond fiber laser continuum at 1.5 μm
      Real-time, ultrahigh-resolution optical coherence tomography (OCT) is demonstrated in the 1.4¿1.7-μm wavelength region with a stretched-pulse, passively mode-locked, Er-doped fiber laser and highly nonlinear fiber. The fiber laser generates 100-mW, linearly chirped pulses at a 51-MHz repetition rate. The pulses are compressed and then coupled into a normally dispersive highly nonlinear fiber to generate a low-noise supercontinuum with a 180-nm FWHM bandwidth and 38 mW of output ...

  2. About Massachusetts Institute of Technology

    Massachusetts Institute of Technology

    Massachusetts Institute of Technology (MIT) is a private, coeducational research university located in Cambridge, Massachusetts. MIT has five schools and one college, containing 32 academic departments, with a strong emphasis in theoretical, applied, and interdisciplinary scientific and technological research.  Laser Medicine and Medical Imaging Group at MIT.  The RLE Laser Medicine and Medical Imaging Group and its close collaborators were the originators of optical coherence tomography (OCT), a diagnostic technology now used in a growing number of medical fields. The group currently works to further understand and exploit the capabilities of OCT technology, with ongoing investigations in topics related to optical coherence microscopy development and optical biopsy using OCT.
