    3. QuaSI: Quantile Sparse Image Prior for Spatio-Temporal Denoising of Retinal OCT Data

      QuaSI: Quantile Sparse Image Prior for Spatio-Temporal Denoising of Retinal OCT Data
      Optical coherence tomography (OCT) enables high-resolution and non-invasive 3D imaging of the human retina but is inherently impaired by speckle noise. This paper introduces a spatio-temporal denoising algorithm for OCT data on a B-scan level using a novel quantile sparse image (QuaSI) prior. To remove speckle noise while preserving image structures of diagnostic relevance, we implement our QuaSI prior via median filter regularization coupled with a Huber data fidelity model ...

    4. Integrated Local Binary Pattern Texture Features for Classification of Breast Tissue Imaged by Optical Coherence Microscopy

      Integrated Local Binary Pattern Texture Features for Classification of Breast Tissue Imaged by Optical Coherence Microscopy
      This paper proposes a texture analysis technique that can effectively classify different types of human breast tissue imaged by Optical Coherence Microscopy (OCM). OCM is an emerging imaging modality for rapid tissue screening and has the potential to provide high resolution microscopic images that approach those of histology. OCM images, acquired without tissue staining, however, pose unique challenges to image analysis and pattern classification. We examined multiple types of texture ...

      Telecom tech continues to advance OCT
      Keep your ear to the ground for an increase in the repurposing for bio applications of technologies designed for non-bio applications, including telecom and automotive. Telecom we've already seenand are continuing to see. Optical coherence tomography ( OCT ) is a good example: This technique, which has substantially impacted ophthalmology and is emerging for many other applications, was enabled by technology developed decades ago for telecommunications. OCT generates volume images at ...

    6. Fully automated lumen segmentation of intracoronary optical coherence tomography images

      Fully automated lumen segmentation of intracoronary optical coherence tomography images
      Optical coherence tomography (OCT) provides high-resolution cross-sectional images of arterial luminal morphology. Traditionally lumen segmentation of OCT images is performed manually by expert observers; a laborious, time consuming effort, sensitive to inter-observer variability process. Although several automated methods have been developed, the majority cannot be applied in real time because of processing demands. To address these limitations we propose a new method for rapid image segmentation of arterial lumen borders ...

    7. The ecosystem that powered the translation of OCT from fundamental research to clinical and commercial impact [Invited]

      The ecosystem that powered the translation of OCT from fundamental research to clinical and commercial impact [Invited]
      25 years is a relatively short period of time for a medical technology to become a standard of care impacting the treatment of millions of people every year. Yet 25 years ago there were no OCT companies, no OCT products, no OCT markets, and only one journal article published using the term OCT (optical coherence tomography). OCT has had a tremendous scientific, clinical, and economic impact on society. Today, it ...

    8. Endoscopic optical coherence tomography angiography microvascular features associated with dysplasia in Barrett's esophagus: a pilot study (with video)

      Endoscopic optical coherence tomography angiography microvascular features associated with dysplasia in Barrett's esophagus: a pilot study (with video)
      Background and Aims Angiogenesis is associated with neoplastic progression of Barretts esophagus (BE). Volumetric optical coherence tomography angiography (OCTA) visualizes subsurface microvasculature without exogenous contrast agents. We investigated the association of OCTA microvascular features with low-grade dysplasia (LGD) and high-grade dysplasia (HGD). Methods Fifty-two patients undergoing BE surveillance or endoscopic eradication therapies for dysplasia were imaged using volumetric OCTA and corresponding histological diagnoses obtained, to yield 97 data sets (non-dysplastic ...

      Macro-scale OCT heralds new industrial uses for the technique
      MIT project achieves 3D OCT over cubic-meter volumes. OCT on a bicycle: imaging cubic-meter volumes The value of optical coherence tomography (OCT) as a technique for micrometer-resolution sub-surface imaging is well established, with new applications now being added to its existing success in ophthalmology and medicine. Its imaging range has usually been restricted to a few centimeters, however, inevitably placing a limit on some of the potential uses for it ...

    13. Cubic meter volume optical coherence tomography

      Cubic meter volume optical coherence tomography
      Optical coherence tomography (OCT) is a powerful three-dimensional (3D) imaging modality with micrometer-scale axial resolution and up to multi-GigaVoxel/s imaging speed. However, the imaging range of high-speed OCT has been limited. Here, we report 3D OCT over cubic meter volumes using a long coherence length, 1310 nm vertical-cavity surface-emitting laser and silicon photonic integrated circuit dual-quadrature receiver technology combined with enhanced signal processing. We achieved 15 m depth resolution ...
