    2. 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 ...

    3. 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 ...

    4. Feature Of The Week: Feature Of The Week 1/26/14: ESPCI-ParisTech Investigates Full-Field Optical Coherence Tomograpy (FF-OCT) Shear Wave Elastography

      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 ...

    5. Full-field optical coherence tomography for the analysis of fresh unstained human lobectomy specimens

      Full-field optical coherence tomography for the analysis of fresh unstained human lobectomy specimens
      Full-field optical coherence tomography (FFOCT) is a real-time imaging technique that generates high-resolution three-dimensional tomographic images from unprocessed and unstained tissues. Lack of tissue processing and associated artifacts, along with the ability to generate large-field images quickly, warrants its exploration as an alternative diagnostic tool. Materials and Methods: One section each from the tumor and from adjacent non-neoplastic tissue was collected from 13 human lobectomy specimens. They were imaged fresh ...

    6. Feature Of The Week 6/9/13: Imaging of Non-Tumorous and Tumorous Human Brain Tissues with Full-Field OCT

      Feature Of The Week 6/9/13: Imaging of Non-Tumorous and Tumorous Human Brain Tissues with Full-Field OCT
      A prospective study was performed on neurosurgical samples from 18 patients to evaluate the use of full-field optical coherence tomography (FF-OCT) in brain tumor diagnosis. FF-OCT captures en face slices of tissue samples at 1 m resolution in 3D to a penetration depth of around 200 m. A 1 cm2 specimen is scanned at a single depth and processed in about 5 min. This rapid imaging process is non-invasive and ...

    7. Large Field, High Resolution Full-Field Optical Coherence Tomography: A Pre-clinical Study of Human Breast Tissue and Cancer Assessment

      Large Field, High Resolution Full-Field Optical Coherence Tomography: A Pre-clinical Study of Human Breast Tissue and Cancer Assessment
      We present a benchmark pilot study in which high-resolution Full-Field Optical Coherence Tomography (FF-OCT) was used to image human breast tissue and is evaluated to assess its ability to aid the pathologists management of intra-operative diagnoses. FF-OCT imaging safety was investigated and agreement between FF-OCT and routinely prepared histopathological images was evaluated. The compact setup used for this study provides 1 mm3 resolution and 200 mm imaging depth, and a ...

    8. Imaging of non tumorous and tumorous human brain tissue with full-field optical coherence tomography

      Imaging of non tumorous and tumorous human brain tissue with full-field optical coherence tomography
      A prospective study was performed on neurosurgical samples from 18 patients to evaluate the use of Full-Field Optical Coherence Tomography (FF-OCT) in brain tumor diagnosis. FF-OCT captures en face slices of tissue samples at 1m resolution in 3D with a typical 200m imaging depth. A 1cm specimen is scanned at a single depth and processed in about 5 minutes. This rapid imaging process is non-invasive and requires neither contrast agent ...

  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.
