      Special Feature Development and Application of Optical Coherence Tomography (OCT)
      To celebrate the 25th anniversary of the introduction of OCT, the special feature issue entitled Development and Application of Optical Coherence Tomography (OCT) had been initiated. OCT originated from low coherence interferometry [1] and was adapted for tomographic imaging in 1991 [2]. In OCT, broad bandwidth light is used in order to produce cross-sectional images of turbid and translucent samples with high axial resolution (in the order of a few ...

      Predicting Macular Edema Recurrence from Spatio-Temporal Signatures in Optical Coherence Tomography Images
      Prediction of treatment responses from available data is key to optimizing personalized treatment. Retinal diseases are treated over long periods and patients response patterns differ substantially, ranging from a complete response to a recurrence of the disease and need for re-treatment at different intervals. Linking observable variables in high-dimensional observations to outcome is challenging. In this paper, we present and evaluate two different data-driven machine learning approaches operating in a ...

      Spectroscopic imaging with spectral domain visible light optical coherence microscopy in Alzheimer’s disease brain samples
      A visible light spectral domain optical coherence microscopy system was developed. A high axial resolution of 0.88 m in tissue was achieved using a broad visible light spectrum (425 685 nm). Healthy human brain tissue was imaged to quantify the difference between white (WM) and grey matter (GM) in intensity and attenuation. The high axial resolution enables the investigation of amyloid-beta plaques of various sizes in human brain tissue ...

      New OCT technique provides better 3-D imaging of the cellular structure of the eye
      Optical Coherence Tomography (OCT) is a high-resolution live imaging technique that can be used for early detection of retinal diseases, such as age-related macular degeneration , diabetes-related conditions, glaucoma or vascular occlusions, for example. However, in order to obtain cellular resolution of the retina and hence even better results, it has so far been necessary to use expensive adaptive lenses to correct the image aberrations that occur. However, using a new ...

      Noniterative digital aberration correction for cellular resolution retinal optical coherence tomography in vivo
      High-resolution imaging of the human retina has always been a challenge due to imperfect optical properties of the human cornea and lens, which limit the achievable resolution. We present a noniterative digital aberration correction (DAC) to achieve aberration-free cellular-level resolution in optical coherence tomography (OCT) images of the human retina in vivo . The system used is a line-field spectral-domain OCT system with a high tomogram rate, reaching 2.5 kHz ...

      Twenty-five years of optical coherence tomography: the paradigm shift in sensitivity and speed provided by Fourier domain OCT
      Optical coherence tomography (OCT) has become one of the most successful optical technologies implemented in medicine and clinical practice mostly due to the possibility of non-invasive and non-contact imaging by detecting back-scattered light. OCT has gone through a tremendous development over the past 25 years. From its initial inception in 1991 [Science 254 , 1178 (1991)] it has become an indispensable medical imaging technology in ophthalmology. Also in fields like cardiology ...

      Introduction to the feature issue on the 25 year anniversary of optical coherence tomography
      This feature issue commemorates the approximately 25 year history of Optical Coherence Tomography (OCT), one of the most successful biophotonic technologies. While OCT has technological origins traceable to ultrafast laser development and fiber optic system test instrumentation of the 1980s, innovations in low coherence interferometry for optical ranging and imaging for biomedical applications in the U.S., Europe and Japan by the early 1990s led to coinage of the now ...

      Conical scan pattern for enhanced visualization of the human cornea using polarization-sensitive OCT
      Conventional imaging of the human cornea with optical coherence tomography (OCT) relies on telecentric scanning optics with sampling beams that are parallel to the optical axis of the eye. Because of the shape of the cornea, the beams have in some areas considerable inclination to the corneal surface which is accompanied by low signal intensities in these areas and thus an inhomogeneous appearance of corneal structures. In addition, alterations in ...

      Polarization Sensitive Optical Coherence Tomography: A Review of Technology and Applications
      Polarization sensitive optical coherence tomography (PS-OCT) is an imaging technique based on light scattering. PS-OCT performs rapid two- and three-dimensional imaging of transparent and translucent samples with micrometer scale resolution. PS-OCT provides image contrast based on the polarization state of backscattered light and has been applied in many biomedical fields as well as in non-medical fields. Thereby, the polarimetric approach enabled imaging with enhanced contrast compared to standard OCT and ...
