    2. Dynamic full field optical coherence tomography: subcellular metabolic contrast revealed in tissues by temporal analysis of interferometric signals

      Dynamic full field optical coherence tomography: subcellular metabolic contrast revealed in tissues by temporal analysis of interferometric signals
      We developed a new endogenous approach to reveal subcellular metabolic contrast in fresh ex vivo tissues taking advantage of the time dependence of the full field optical coherence tomography interferometric signals. This method reveals signals linked with local activity of the endogenous scattering elements which can reveal cells where other imaging techniques fail or need exogenous contrast agents. We benefit from the micrometric transverse resolution of full field OCT to ...

    3. Fingerprint imaging from the inside of a finger with full-field optical coherence tomography

      Fingerprint imaging from the inside of a finger with full-field optical coherence tomography
      Imaging below fingertip surface might be a useful alternative to the traditional fingerprint sensing since the internal finger features are more reliable than the external ones. One of the most promising subsurface imaging technique is optical coherence tomography (OCT), which, however, has to acquire 3-D data even when a single en face image is required. This makes OCT inherently slow for en face imaging and produce unnecessary large data sets ...

    4. Assessment of Sentinel Node Biopsies With Full-Field Optical Coherence Tomography

      Assessment of Sentinel Node Biopsies With Full-Field Optical Coherence Tomography
      Current techniques for the intraoperative analysis of sentinel lymph nodes during breast cancer surgery present drawbacks such as time and tissue consumption. Full-field optical coherence tomography is a novel noninvasive, high-resolution, fast imaging technique. This study investigated the use of full-field optical coherence tomography as an alternative technique for the intraoperative analysis of sentinel lymph nodes. Seventy-one axillary lymph nodes from 38 patients at Tenon Hospital were imaged minutes after ...

    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 ...

    6. Full-Field Optical Coherence Tomography of Human Donor and Pathological Corneas

      Full-Field Optical Coherence Tomography of Human Donor and Pathological Corneas
      Purpose : To evaluate the performance of a full-field optical coherence tomography (FF-OCT) system in the study of human donor and pathological corneas and assess its suitability for use in eye banks. Methods : Our study was carried out using an FF-OCT system developed for non-invasive imaging of tissue structures in depth with ultrahigh resolution (1m in all directions). Images were acquired from eight stored human donor corneas (either edematous or after ...

    7. High resolution in-vivo imaging of skin with full field optical coherence tomography

      High resolution in-vivo imaging of skin with full field optical coherence tomography
      Full-field OCT (FFOCT) has the ability to provide en-face images with a very good axial sectioning as well as a very high transverse resolution (about 1 microns in all directions). Therefore it offers the possibility to visualize biological tissues with very high resolution both on the axial native view, and on vertical reconstructed sections. Here we investigated the potential dermatological applications of in-vivo skin imaging with FFOCT. A commercial FFOCT ...

    9. From supersonic shear wave imaging to full-field optical coherence shear wave elastograph

      From supersonic shear wave imaging to full-field optical coherence shear wave elastograph
      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 ...
