    2. Optical tissue sectioning using full field optical coherence tomography

      Optical tissue sectioning using full field optical coherence tomography
      According to a first aspect, the invention relates to a multimodal optical sectioning microscope (200, 400, 600) for full-field imaging of a volumic and scattering sample comprising: --a full-field OCT system for providing an image of a first section in depth of the sample comprising an illumination sub-system (201, 401, 601) and a full-field imaging interferometer with a detection sub system (208, 408, 608) and an optical conjugation device for ...

    3. Rapid evaluation of fresh ex vivo kidney tissue with full-field optical coherence tomography

      Rapid evaluation of fresh ex vivo kidney tissue with full-field optical coherence tomography
      Background: Full-field optical coherence tomography (FFOCT) is a real-time imaging technique that rapidly generates images reminiscent of histology without any tissue processing, warranting its exploration for evaluation of ex vivo kidney tissue. Methods: Fresh tissue sections from tumor and adjacent nonneoplastic kidney ( n = 25 nephrectomy specimens; clear cell renal cell carcinoma (CCRCC) = 12, papillary RCC (PRCC) = 4, chromophobe RCC (ChRCC) = 4, papillary urothelial carcinoma (PUC) = 1, angiomyolipoma (AML) = 2 and ...

    4. Method and device for high resolution full field interference microscopy

      Method and device for high resolution full field interference microscopy
      The invention relates to an incoherent light full field interference microscopy device for the imaging of a volumetric scattering sample (106). The device comprises an interference device (100) between a reference wave (401), produced by reflection of an incident wave by a reflective surface (105) of a reference arm of the interference device, and an object wave (402) produced by backscattering of the incident wave by a slice of the ...

    5. Anisotropic polyvinyl alcohol hydrogel phantom for shear wave elastography in fibrous biological soft tissue: a multimodality characterization

      Anisotropic polyvinyl alcohol hydrogel phantom for shear wave elastography in fibrous biological soft tissue: a multimodality characterization
      Shear wave elastography imaging techniques provide quantitative measurement of soft tissues elastic properties. Tendons, muscles and cerebral tissues are composed of fibers, which induce a strong anisotropic effect on the mechanical behavior. Currently, these tissues cannot be accurately represented by existing elastography phantoms. Recently, a novel approach for orthotropic hydrogel mimicking soft tissues has been developed (Millon et al 2006 J. Biomed. Mater. Res. B 30511). The mechanical anisotropy is ...

      Feature Of The Week: Feature Of The Week 1/26/14: ESPCI-ParisTech Investigates Full-Field Optical Coherence Tomograpy (FF-OCT) Shear Wave Elastography
      Elasticity maps of tissue have proved to be particularly useful in providing complementary contrast to ultrasonic imaging, e.g., for cancer diagnosis at the millimeter scale. Optical coherence tomography (OCT) offers an endogenous contrast based on singly backscattered optical waves. Adding complementary contrast to OCT images by recording elasticity maps could also be valuable in improving OCT-based diagnosis at the microscopic scale. Static elastography has been successfully coupled with full-field ...

  2. About Claude Boccara

    Claude Boccara

    A. Claude Boccara was Dean of Research at ESPCI-ParisTech. Among the optical methods he has developed new microscopies to increase depth and lateral resolution. Recently, ultimate measurements have found new fields of application going from detection of gravitational waves to 3-D imaging though scattering media. He has published more than 300 scientific articles (ISI/ Boccara A* or Boccara C) in international journals. In 2007 he founded the start-up LLTech devoted to medical imaging and diagnostics.

  3. Quotes

    1. The system provides pictures of excellent quality that you can browse easily from the centimeter down to the micrometer scale. I confess having been amazed by the results. This new tool already makes my fellows biologists and physicians enthusiastic: its worth trying it, you will like it.
      In LLTech launches the ultra high resolution - micron level - 3D Light-CT scanner for research
    2. "The CT principle involves using light with a relatively broad spectrum, and the broader the spectrum is, the better the sectioning ability of the technique...That illumination commonly comes from a superluminescent diode or an ultrashort pulsed laser, but Light-CT is completely different.
      In LLTech brings optical biopsies to operating theaters: Coherence tomography technique allows surgeons to see biopsy results in 3D and almost real-time.
