    1. In vivo imaging through the entire thickness of human cornea by full-field optical coherence tomography

      In vivo imaging through the entire thickness of human cornea by full-field optical coherence tomography
      Despite obvious improvements in visualization of the in vivo cornea through the faster imaging speeds and higher axial resolutions, cellular imaging stays unresolvable task for OCT, as en face viewing with a high lateral resolution is required. The latter is possible with FFOCT, a method that relies on a camera, moderate numerical aperture (NA) objectives and an incoherent light source to provide en face images with a micrometer-level resolution. Recently ...

    2. Quality control and primo-diagnosis of transurethral bladder resections with full-field OCT

      Quality control and primo-diagnosis of transurethral bladder resections with full-field OCT
      Transurethral resections are commonly used for bladder cancer diagnosis, treatment and follow-up. Cancer staging relies largely on the analysis of muscle in the resections; however, muscle presence is uncertain at the time of the resection. An extemporaneous quality control tool would be of great use to certify the presence of muscle in the resection, and potentially formulate a primo-diagnosis, in order to ensure optimum patient care. Full-field optical coherence tomography ...

    3. High efficiency for prostate biopsy qualification with full-field OCT after training

      High efficiency for prostate biopsy qualification with full-field OCT after training
      Full-field optical coherence tomography (FFOCT) offers a fast and non-destructive method of obtaining images of biological tissues at ultrahigh resolution, approaching traditional histological sections. In the context of prostate cancer diagnosis involving multiple biopsies, FFOCT could be used to validate the cores just after they are obtained in order to guide the number of biopsies to be performed. The aim of the study was to define and test a training ...

    4. A feasibility study of full-field optical coherence tomography for rapid evaluation of EUS-guided microbiopsy specimens

      A feasibility study of full-field optical coherence tomography for rapid evaluation of EUS-guided microbiopsy specimens
      Background Rapid on-site evaluation of cytologic specimens is a way of determining the adequacy of fine-needle aspiration (FNA). However, alternatives may be useful when the presence of a cytotechnologist and/or pathologist is not possible. Objective To evaluate the feasibility of using full-field optical coherence tomography (FFOCT) for FNA specimen quality assessment. Design FFOCT images were acquired on gastric, pancreatic, pelvic, and lymph-node formalin-fixed FNA specimens and were compared with ...

    5. 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 ...

    6. Full field optical coherence tomography of prostate biopsies: A step towards pre-histological diagnosis?

      Full field optical coherence tomography of prostate biopsies: A step towards pre-histological diagnosis?
      Objectives To evaluate the value of full field optical coherence tomography (FFOCT) for cancer detection on prostate biopsies Patients and methods Eight consecutive patients who underwent prostate biopsies for an elevated PSA or suspicious DRE findings were included in the study. For each patient, one to three biopsy cores were imaged with FFOCT immediately after sampling. Images obtained were analyzed by a pathologist blinded to the pathological results, and classified ...

    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. Full-field optical coherence tomography: a new technology for 3D high resolution skin imaging

      Full-field optical coherence tomography: a new technology for 3D high resolution skin imaging
      Background/Aims : Full-field optical coherence tomography (FFOCT) is a new imaging technology that can provide 3D micron-level resolution and is suited for high resolution imaging of biological tissue. The aim of this study is to evaluate its capacity and potential for imaging human epidermis and dermis and various skin pathologies in ex- and in-vivo conditions. Methods : Non fixed and fixed samples of normal and pathological skin and normal in-vivo skin ...

    9. Multimodal full-field optical coherence tomography on biological tissue: toward all optical digital pathology

      Multimodal full-field optical coherence tomography on biological tissue: toward all optical digital pathology
      Optical Coherence Tomography (OCT) is an efficient technique for in-depth optical biopsy of biological tissues, relying on interferometric selection of ballistic photons. Full-Field Optical Coherence Tomography (FF-OCT) is an alternative approach to Fourier-domain OCT (spectral or swept-source), allowing parallel acquisition of en-face optical sections. Using medium numerical aperture objective, it is possible to reach an isotropic resolution of about 1x1x1 m. After stitching a grid of acquired images, FF-OCT gives ...
